…igning aws_credentials collapsed refreshable providers into a static Aws::Credentials snapshot, so requests kept being signed with an STS token that expires after 1 hour by default. Passing the provider itself as credentials_provider lets Aws::Sigv4::Signer fetch fresh credentials for every request. Passing refresh_credentials_interval as the STS duration_seconds (fluent#78) was reverted in fluent#108, so it is not revisited here.

With
assume_role_arn,aws_credentialscollapsed the refreshable provider into a staticAws::Credentialssnapshot, so SigV4 kept signing with the STS token after it expired (1 hour by default) and the cluster answered 403The security token included in the request is expireduntil the plugin was restarted.This keeps the provider object and passes it to the signer as
credentials_provider, soAws::Sigv4::Signerfetches fresh credentials for every request.Passing
refresh_credentials_intervalas the STSduration_seconds(#78) was reverted in #108, so that approach is not revisited here.Fixes #188
