Grafana 5.4 on AWS running w/ an IAM roll for access to cloudwatch metrics. I am intermittently getting an error on some panels and not others.
NoCredentialProviders: no valid providers in chain. Deprecated. For verbose messaging see aws.Config.CredentialsChainVerboseErrors
i can refresh the panel and the failing ones will then work… its very intermittent and only happening for the cloudwatch metrics.
