To get started, clone the boilerplate we will be using in this example: Then, cd into the directory & install the dependencies using yarn or npm: Now that the dependencies are installed, we will use the AWS Amplify CLI to initialize a new project. "Private" implies that there is Cognito / Federated Identity User or Group Authorization, either dynamic or static groups, and/or User (Owner) authorization. Someone suggested on another thread to use custom-roles.json but that also didn't help despite me seeing changes reflecting with the admin roles into the vtls. Thanks for contributing an answer to Stack Overflow! Choose the AWS Region and Lambda ARN to authorize API calls To learn how to provide access to your resources across AWS accounts that you own, see Providing access to an IAM user in another AWS account that you Closing this issue. ', // important to make sure we get up-to-date results, // Helps log out errors returned from the AppSync GraphQL server. Please let me know if it fixes the problem for you or not. { allow: groups, groupsField: "editors" }, This is the intended functionality. When using the AppSync console to create a Very informative issue, and it's already included in the new doc, https://docs.amplify.aws/lib/graphqlapi/graphql-from-nodejs/q/platform/js. encounter when working with AWS AppSync and IAM.

Finally, here is an example of the request mapping template for editPost, Other relevant code would be my index.js: And the schema definition for the User object: Ultimately, I'm trying to make something similar to this example. Jordan's line about intimate parties in The Great Gatsby? & Request.ServerVariables("QUERY_STRING") 13.global.asa? As an application data service, AppSync makes it easy to connect applications to multiple data sources using a single API. This was really helpful. @danrivett - Could you please clarify on the below? mode and any of the additional authorization modes. Note that the OIDC token can be a Bearer scheme. First, your addPost mutation GraphQL query via curl as follows: Lambda functions are called before each query or mutation, but their return value is the post. (typename.fieldname) The Lambda authorization token should not contain a Bearer scheme prefix. When using Lambda functions for authorization, the template. I just spent several hours battling this same issue. authorization token. However, nothing I did on the schema was effective (including adding @aws_cognito_user_pools as indicated). 6. After that, $adminRoles contained the correct environment's lambda ARNs and I no longer received the "Unauthorized" error in GraphQL. this, you might give someone permanent access to your account. You can do this I'm still not sure is 100% accurate because that would seem to short certain authorization checks. AppSync supports multiple authorization modes to cater to different access use cases: As documented here, adding the roles (arn:aws:sts::XXX:assumed-role/appsync-user-created-handler-dan-us-west-2-lambdaRole/appsync-user-created-handler in your case) to custom-roles.json file (then amplify push) should give the necessary access. you can specify an unambiguous field ARN in the form of @danrivett - How are you signing the GraphQL request from Lambda outside amplify project? Now that we have a way to identify the user in a mutation, lets make it to where when a user requests the data, the only fields they can access are their own. (such as an index on Author). I see a custom AuthStrategy listed as an allowed value. authorization token is of the correct format before your function is called. review the Resolver Today we are announcing a new authorization mode (AWS_LAMBDA) for AppSync leveraging AWS Lambda serverless functions. object only supports key-value pairs. Keys, and their associated metadata, could be stored in DynamoDB and offer different levels of functionality and access to the AppSync API. :/ relationship will look like below: Its important to scope down the access policy on the role to only have permissions to is trusted to assume the role. Unfortunately, the Amplify documentation does not do a good job documenting the process. These regular expressions are used to validate that an Have a question about this project? Hello, seems like something changed in amplify or appsync not so long time ago. getAllPosts in this example). authorization modes. editors: [String] the root Query, Mutation, and Subscription For example, thats the case for the By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. @sundersc we are using the aws-appsync package and the following code that we have in an internal reusable library: This makes the AppSync interaction from Lambda very simple as it just needs to issue appSyncClient.query() or appSyncClient.mutate() requests and everything is configured and authenticated automatically. I had the same issue in transformer v1, and now I have it with transformer v2 too. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. When using private, you give some permissions to everyone with a valid JWT token from the configured Cognito User Pool. that any type that doesnt have a specific directive has to pass the API level AWS AppSync. modes, Fine-grained logic, which we describe in Filtering So I think this issue comes from me not quite understanding the relationship between AWS cognito user pools and the auth rules in a graphql schema. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. With Lambda authorization you specify a Lambda function with custom business logic that determines if requests should be authorized and resolved by AppSync. A JSON object visible as $ctx.identity.resolverContext in resolver regular expression. When sharing an authorization function between multiple APIs, be aware that short-form It expects to retrieve an RFC5785 So the above explains why the generated v2 auth Pipeline Resolver is returning unauthorized but I can't find anything to explain why this behaviour has changed from v1, and what the expected change on our end should be for it to work. This issue has been automatically locked since there hasn't been any recent activity after it was closed. arn:aws:appsync:us-east-1:111122223333:apis/GraphQLApiId/types/TypeName/fields/FieldName Since we ran into this issue we reverted back to the v1 transformer in order to not be blocked, and so our next attempt to move to v2 is back in our backlog but we hope to work on in the next 4-6 weeks if we're unblocked. { "adminRoleNames": ["arn:aws:sts::<AccountIdHere>:assumed-role"] } If you want to use the AppSync console, also add your username or role name to the list as mentioned here. This also fixed the subscriptions for me. If you want to set access controls on the data based on certain conditions Sign in The total size of this JSON object must not exceed 5MB.

After the error is identified and resolved, reroute the API mapping for your custom domain name back to your HTTP API. (auth_time). The text was updated successfully, but these errors were encountered: Hi @ChristopheBougere, try this @auth rule addition on your types: If you want to also use an API Key along with IAM and Cognito, use this: Notice I added new rules, and modified your original owner and groups rules. compliant JSON document at this URL. The code example shows to use { allow: private, provider: iam } as mentioned here, and how to sign the request. privacy statement. { allow: public, provider: iam, operations: [read] } directives against individual fields in the Post type as shown To change the API Authorization default mode you need to go to the data modeling tool of aws amplify and from there (below the title) there's the link to "Manage API authorization mode & keys". authorization token. I did take a look at your suggestion briefly though, and without testing it, I agree with you that I think it should work, if I've identified and understood the relevant code line in iamAdminRoleCheckExpression() correctly. Newbies like me: Keep in mind the role name was the short one like "trigger-lambda-role-oyzdg7k3", not the full ARN. We are getting Unauthorized in the mutation - "Not Authorized to access updateFarmer on type Mutation" In our resolver, we look for certain data, in our case the users username, to either conditionally perform operations, query based on the current user, or create mutations using the currently logged in users username. We could of course brute force it by just replacing all auth VTL resolvers to remove that if-block, but that isn't something we are considering because of the maintenance overhead as auto-generated VTL resolvers evolve over time. type and restrict access to it by using the @aws_iam directive. The problem is that the auth mode for the model does not match the configuration. Now that our Amplify project is created and ready to go, lets create our AWS AppSync API. 1. and there might be ambiguity between common types and fields between the two The GraphQL Transform library allows you to deploy AWS AppSync GraphQL APIs with features like NoSQL databases, authentication, elasticsearch engines, lambda function resolvers, relationships, authorization, and more using GraphQL schema directives. We can raise a separate ticket for this aswell. You can use private with userPools and iam. Recommended way to query AppSync with full access from the backend (multiple auth), https://aws-amplify.github.io/docs/cli-toolchain/graphql?sdk=js#private-authorization. For example, you can add a restrictedContent field to the Post If you lose your secret access key, you must add new access keys to your IAM user. Navigate to the Settings page for your API. mapping template. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant Self-Service Users Login: https://my.ipps-a.army.mil. You can start using Lambda authorization in your existing and new APIs today in all the regions where AppSync is supported. This makes sense to me because IAM access is guarded by IAM policies assigned to the Lambda which provide coarse or fine-grained AppSync API access. However, you cant use reference this: Note that you can omit the @aws_auth directive if you want to default to a the API ID and the authentication token. "No current user": Isn't it even possible to make unauth calls to AWS AppSync through Amplify with authentication type AMAZON_COGNITO_USER_POOLS? Next, well update a couple of resolvers. of this section) needs to perform a logical check against your data store to allow only the AppSync sends the request authorization event to the Lambda function for evaluation in the following format: 4. Can you please also tell how is owner different from private ? The Lambda function executes its authorization business logic and returns a payload to AppSync: The isAuthorized field determines if the request should be authorized or not. the Post type with the @aws_api_key directive. Each item is either a fully qualified field ARN in the form of In that case you should specify "Cognito User Pool" as default authorization method. The same example above now means: Owners can read, update, and delete. @auth( 3. Let me know in case of any issues. Use the following information to help you diagnose and fix common issues that you might Your Click Save Schema.

The function overrides the default TTL for the response, and sets it to 10 seconds. 2023, Amazon Web Services, Inc. or its affiliates. the user identity as an Author column: Note that the Author attribute is populated from the Identity Similarly cognitoIdentityPoolId and cognitoIdentityId were passed in as null when executed from the Lambda execution. Well also show how to properly identify the currently authenticated user in a secure way in AWS AppSync, storing their username in the database as their unique identifier when they create resources. A request sent with curl would look like this: Note that AppSync does not support unauthorized access. What solved it for me was adding my Lambda's role name to custom-roles.json per @sundersc 's workaround suggestion. The problem is that Apollo don't cache query because error occurred. There seem to be several issues related to this matter, and I don't think the migration docs explain the resolver change adequately.
