Grafana 5.4 -> 6.7 Upgrade Issues

Hello,

Recently, we have upgraded our Grafana from 5.4 to 6.7 version. After the upgrade, we noticed that our cloud watch data source is not connecting and showing exceptions when we save and test.

We are using role used authentication and the role has sufficient permissions. It was working fine in 5.4

After doing some research, I found this thread which says about the error we faced - https://github.com/grafana/grafana/issues/16725

Is it fixed in latest version or we have to move to credentials file based authentication. Our setup is in AWS so we prefer the role based authentication.

Thanks

Is it fixed in 7.0.3 ?
