Unable to Get API Resource information from API Hub using Java Client Library

[dsam0162]

I'm using the following libraries to configure the Apihub Java Client to the Gradle project.

• implementation platform('com.google.cloud:libraries-bom:26.45.0')
• implementation 'com.google.cloud:google-cloud-apihub'
• implementation group: 'com.google.auth', name: 'google-auth-library-oauth2-http', version: '1.24.0'

However, I'm getting a permission error that is blocking me from invoking any of the ApiHubClient methods. I'm using an access token retrieved from Google Cloud SDK using the command (gcloud auth print-access-token) which has all the necessary permissions to access the APIHub resources. Also, the API Hub Rest APIs are working without issues using the same access token.

Environment details

Java version: 17

Steps to reproduce

(Replace "access-token-here" and put valid values for API name details(project,location,api-id) in the code snippet.)

1. Create a GoogleCredentials object using an Access token obtained from Google Cloud SDK which has all necessary permissions,
2. Pass the credentials object as a credential provider for ApiHubSettings
3. Initialize the ApiHubClient using created ApiHubSettings
4. Run Java code snippet

Code example

GoogleCredentials credentials = GoogleCredentials.create(AccessToken.newBuilder().setTokenValue("access-token-here").build());

ApiHubSettings apiHubSettings = ApiHubSettings.newBuilder()
    .setCredentialsProvider(()->credentials)
    .build();

//Get Api Resource Details
try (ApiHubClient apiHubClient = ApiHubClient.create(apiHubSettings)) {
   GetApiRequest request =
       GetApiRequest.newBuilder()
           .setName(ApiName.of("xyz-apigee-sbx", "us-central2", "200ab164-97cb-479e-9451-98e42bae1563")
               .toString())
           .build();
   Api response = apiHubClient.getApi(request);
   logger.info("Response: {}",response);
} catch (Exception e) {
   logger.error("An error occurred while processing: {}", e.getMessage(), e);
}

Stack trace

com.google.api.gax.rpc.PermissionDeniedException: io.grpc.StatusRuntimeException: PERMISSION_DENIED: Read access to project 'xyz-apigee-sbx' was denied

@dsam0162 - I used

ApiHubSettings hubSettings = ApiHubSettings.newBuilder()
                .setCredentialsProvider(FixedCredentialsProvider.create(credentials))
                .build();

and it worked for me

I use it in https://github.com/apigee/apigee-apihub-maven-plugin

Thanks @ssvaidyanathan This fix worked for the following Gradle dependency as well. 🎉🎉🎉

• implementation 'com.google.cloud:google-cloud-apihub'

@dsam0162 - Glad it worked

Can this issue be closed then?
