Verify that the service account has the necessary RBAC (Role-Based Access Control) permissions to access the Kubernetes resources (e.g., pods, secrets, configmaps) required by your ML application. Check the service account's role bindings and ensure they align with the resource's policies. Also, confirm the service account token is valid and hasn't expired.
