Google Cloud Build Erroneous "Exit Status 1" Bug

We seem to be having an issue with our builds at the moment where they are successful (the docker image gets built and pushed to the appropriate container registry) but Circle seems to indicate that it is getting a CircleCI received exit code 1 back. However as far as the logs show (both in circle and in GCloud build logs) there are no errors returned or any indication that anything went wrong. Are there current or known issues using cloud build at the moment?
