I have a GKE cluster with "https://www.googleapis.com/auth/trace.append" scope enabled.
node.js client library is used as the first line as written in the docs. I get 403.
ERROR:@google-cloud/trace-agent: TraceWriter: error: 403 ApiError: The caller does not have permission
Did you add the trace.append OAuth scope when creating the cluster as the docs describe?
gcloud container clusters create example-cluster-name --scopes https://www.googleapis.com/auth/trace.append
