Github user ijokarumawak commented on the issue: https://github.com/apache/nifi/pull/2943 Hello @jugi92 , thank you very much for your contribution. I stumble upon the same needs and wanted to merged this urgently. Currently, GCP processors do not work if they run on a server which doesn't have direct internet connection and requires forward proxy to go out. Because GCPCredentialControllerService doesn't support proxy configuration. I am going to create my own PR based on your commit to fix the conflict. I will review your change at the same time and make change if necessary. I hope this approach helps the PR to get merged quickly. Will update you once the new PR is ready. Thanks!
