  Tracing crossplane creation and errors can be done by tracing your custom resource. But you might have to trace errors in the underlying provider resources as well.

  crossplane beta trace my-custom-resource-type my-custom-resource-name
  crossplane beta trace bucketpolicy.s3.aws.upbound.io my-custom-resource-name
  # Need kubectl to find more verbose messages about
  kubectl get bucketpolicy.s3.aws.upbound.io my-custom-resource-name -oyaml

  Stern isn’t that great to use to filter log messages in if you do not know jq/don’t have JSON format available but it is possible to escape characters when you use include.

  stern -c istio-proxy -i '\"response_code\":200,' .
  stern -c istio-proxy -i '\"response_flags\":UH' .
  stern -c istio-proxy -i '\"response_flags\":\"-\"' .
