Cause

This is the result of an invalid credential.  In this case the private_key was incorrect. 

Solution

Review the jsom created for the service account and input the credentials correctly.  On a side note, verify the private_key used does not have "\n".  When you look at the created jsom file, in a basic text editor, each line of the private_key ends with \n. You must replace each instance of \n with an actual carriage return.
