Mender deployment 2.5.0 correctly reading S3 configuration

After upgrading to 2.5.0 I found that the deployment container would not start.

Current working configuration is;
aws uri, is set in the config.yml and replace the one in the container (via docker volume mount), docker env DEPLOYMENTS_AWS_URI appears to be ignored.

DEPLOYMENTS_AWS_REGION set in docker env, aws region set in config.yml appears to be ignored.

Would appreciate instruction on obtaining more detailed debug, I’m working from deployment docker logs and tcpdump.
