Cloudwatch NoCredentialProviders Attempting to Use Web Token in Kubernetes

Grafana v8.4.3 in Kubernetes. I’m trying to use the web token injected by AWS EKS in the pod to assume a role in another account, but based on the logs that I’m seeing, it’s not able to find credentials because it’s only looking in environment variables and the EC2 metadata service.

The following command works and assumes roles properly (I’m able to access cloudwatch data successfully): aws sts get-caller-identity and aws cloudwatch list-metrics

Does Grafana not support AssumeWithWebToken yet?
