[ERROR] the local copy message must have path set.

Hi Firecloud Team,

I submitted a workflow to FC yesterday. But, just one of the tasks was failed. I tried three times and got the same ERROR message as following in workflow.log. And, there is no log files for the failed task. I have no idea how to fix it. Thank you very much!
