Describe the bug

Tried to create a job with "outputFiles" and in the "containerUrl" I accidently didn't mention the protocol. The command failed with an unexpected error that prevented me from getting the real validation error (see attached call stack)

The only way I was able to get around it and get the real validation issue was by monkey-patching custom_errors.CreateTasksErrorException.__init__ and adding a dummy message to the error.

Command Name
az batch job create Extension Name: azure-batch-cli-extensions. Version: 6.0.0.

Errors:

CLIInternalError: The command failed with an unexpected error. Here is the traceback:
