`WebIdentityTokenCredentialsProvider(): No op collector does not support createChild` since 2.13.52

[tylerwilding-wk]

When attempting to include the STS dependency to allow for Web Identity Token's to be retrieved from the environment/container, the following error is produced - ... WebIdentityTokenCredentialsProvider(): No op collector does not support createChild ...

I traced this particular error down to this PR, where a comment specifically mentioned that this could lead to a problem #1938 (comment) when the NoOpMetricCollector is used.

I wasn't able to find a suitable workaround other than downgrading the dependency to exclude these changes. The code in question had no metric configuration whatsoever, so I'm assuming that the NoOpMetricCollector was instantiated behind the scenes. Likewise I couldn't find a way to completely disable metrics (to avoid even the NoOp collector).

Hi @tylerwilding-wk, can you provide a sample code we can use to reproduce the issue?

@tylerwilding-wk Actually it looks like this is fixed in the latest release 2.14.0. Can you try it out and check if you still see the issue?

Sorry it's taken me so long to respond. Running the latest version 2.14.4 I'm running into a new problem. Looks like the WebIdentityTokenCredentialsProvider() was removed from the default credential chain. It was using this provider with STS that was causing the original error.

Before:

Exception in thread "main" software.amazon.awssdk.core.exception.SdkClientException: Unable to load credentials from any of the providers in the chain AwsCredentialsProviderChain(credentialsProviders=[SystemPropertyCredentialsProvider(), EnvironmentVariableCredentialsProvider(), WebIdentityTokenCredentialsProvider(), ProfileCredentialsProvider(), ContainerCredentialsProvider(), 

Now:

Exception in thread "main" software.amazon.awssdk.core.exception.SdkClientException: Unable to load credentials from any of the providers in the chain AwsCredentialsProviderChain(credentialsProviders=[SystemPropertyCredentialsProvider(), EnvironmentVariableCredentialsProvider(), ProfileCredentialsProvider(), ContainerCredentialsProvider(), InstanceProfileCredentialsProvider()]) : 

In terms of sample code to reproduce, I'm just trying to list contents from an S3 bucket:

S3Client s3 = S3Client.builder().build();
ListObjectsV2Request listReq = ListObjectsV2Request.builder().bucket(NAME_OF_BUCKET).build();
ListObjectsV2Iterable pages = s3.listObjectsV2Paginator(listReq);
pages.forEach(
        (ListObjectsV2Response page) -> {
          page.contents()
              .forEach(
                    .... // process objects
              });
        });
}

Can you provide the full stacktrace?
