I have created a Jira - NIFI-5156 <https://issues.apache.org/jira/browse/NIFI-5156> and made the necessary changes to the current nifi-gcp-bundle. I have tested the components - GCS Processors & GCP Credentials Service. They all work as expected. Anyone want to give it a look and review the changes? PR #2680 <https://github.com/apache/nifi/pull/2680>
