mobile: AWSPhone! I'm in the process of migrating our existing Amplify GraphQL API (AppSync) over to use the GraphQL Transformer v2 however I'm running into an unexpected change in IAM authorization rules that do not appear to be related (or at least adequately explained) by the new general deny-by-default authorization change. Essentially, we have three roles in the admin tool: Admin: these are admin staffs from the client's company. On empty result error is not necessary because no data returned. Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. If you haven't already done so, configure your access to the AWS CLI. To learn more, see our tips on writing great answers. Thinking about possible solutions a little bit more, in case it's helpful, I thought of a couple of possibilities: This is based on looking at the amplify-graphql-auth-transformer source code here. can mark a field using the @aws_api_key directive (for example, this, you might give someone permanent access to your account.

I ask since it's not a change we'd like to consume given we already secure AppSync access through IaC IAM policies as mentioned above, even though the rest of the v2 changes look great. wishList: [String] For example, you can add a restrictedContent field to the Post You can use the isAuthorized flag to tell AppSync if the user is authorized to access the AppSync API or not. The preferred method of authorization relies on IAM with tokens provided by Cognito User Pools or other OpenID Connect providers. If a response cache TTL has been set, AppSync evaluates whether there is an existing unexpired cached response that can be used to determine authorization. This information is available in the AppSync resolvers context identity object: The functions denies access to thecommentsfield on theEventtype and thecreateEvent mutation. Have a question about this project? relationship will look like below: Its important to scope down the access policy on the role to only have permissions to to your account.

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. Use the drop down to select your function ARN (alternatively, paste your function ARN directly). cached: repeated requests will invoke the function only once before it is cached based on Keys, and their associated metadata, could be stored in DynamoDB and offer different levels of functionality and access to the AppSync API. These Lambda functions are managed via the Serverless Framework, and so they aren't defined as part of the Amplify project. Each item is either a fully qualified field ARN in the form of To add this functionality using our existing setup, we only need to do one thing: update the listCities resolver to query only for the data created by the currently logged in user. @PrimaryKey By the way, it's not necessary to add anything to @auth when using the custom-roles.json workaround. is trusted to assume the role.

The text was updated successfully, but these errors were encountered: I would also add that this is currently a blocker for us to continue our migration from the v1 transformer to the v2 transformer, until we find a good solution to the problem above. identity information in the table for comparison. the schema. authorization modes or the AMAZON_COGNITO_USER_POOLS authorization mode I believe it's because amplify generates lambda IAM execution role names that differ from lambda's name. would be for the user to gain credentials in their application, using Amazon Cognito User { "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. directives against individual fields in the Post type as shown 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. I did try the solution from user patwords. I removed, then amplify pushed, and recreated the table and it worked. Better yet and more descriptive would be to introduce a new AuthStrategy perhaps named resource to reflect that resource-based IAM permissions are being used and not role-based? the AWS AppSync GraphQL API. Connect and share knowledge within a single location that is structured and easy to search. You can specify different clients for your Thanks for letting us know this page needs work. mapping Set the adminRoleNames in custom-roles.json as shown below.

From my interpretation of the custom-roles.json's behavior, it looks like it appends the values in the adminRoleNames into the GraphQL vtl auth resolvers' $authRoles. information is encoded in a JWT token that your application sends to AWS AppSync in an Now, lets go back into the AWS AppSync dashboard. Thanks for letting us know we're doing a good job! contain JSON fields of kty and kid. Seems like an issue with pipeline resolvers for the update action. After changing the schema, go to the CLI, and write amplify update auth follow this image: Thanks for contributing an answer to Stack Overflow! In my case we have local scripts accessing the graphql API via aws access keys, adding this to custom-roles.json resolved the issue: Hi, authorized. restrict the readers so that they cannot add new entries, then your schema should look like Not Authorized to access createEvent on type Mutation Even though I'm logged in with a user from Cognito, the API is accessed with the API key. I've tried reading the aws amplify docs but haven't been able to properly understand how the graphql operations are effected by the authentication. @sundersc yes the lambdas are all defined outside of the Amplify project as we have an Event Driven Architecture on the backend. Change the API-Level authorization to If you are not already familiar with how to use AWS Amplify with Cognito to authenticate a user and would like to learn more, check out either React Authentication in Depth or React Native Authentication in Depth.

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. Regarding the option to add roles to custom-roles.json that isn't a very practical option for us unfortunately since those role names change per environment, and to date we have over 60 Lambda functions (each with their own IAM policies) and we'd need to update custom-roles.json each time we create a new Lambda that accesses AppSync. reference. The default V2 IAM authorization rule tries to keep the api as restrictive as possible. I would expect that Amplify would build the project according to the CLI's parameters such as the checked out environment before runninf amplify push, but this not the case currently.

Using AppSync, you can create scalable applications, including those requiring real . If the user isn't supposed to be able to access the data period because of a fixed role permission, this would still result in inconsistent behavior. The supported request types are queries (for getting data from the API), mutations(for changing data via the API), and subscriptions(long-lived connections for streaming data from the API). Unless there is a compelling reason not to support the old IAM approach, I would really like the resolver to provide a way of not adding that #if( $util.authType() == "IAM Authorization" ) block and instead leave it up to the IAM permission assigned to the Lambda, but I don't know what negative security implications that could entail.
