Issue with malformed json when getting kubectl logs

[noahlwest]

I noticed this while trying to create the eval in #295, it happens quite often when trying to list data from kubectl logs.

ran with ./cmd --v 5 --enable-tool-use-shim

  The user wants to check the logs of the  eval-app-pod  in the  app-level-   
  fails-                                                                      
  test  namespace for any issues. I will use  kubectl logs  to retrieve the   
  logs for this pod. Since the pod has only one container ( eval-app-executor 
  as seen in a previous event), I don't need to specify the container name.   


  Running: kubectl logs pod/eval-app-pod -n app-level-fails-test
