I have a map reduce which triggers another map/reduce using the N/task module. It has been working fine for many months, and suddenly, without the code being touched, it stopped working both in Sandbox and Production with an error message of

Unexpected Error

It breaks when running the function

myTask.submit()

Anything change that might be breaking that?

unexpected error by itself isnt much to go by

And the standard if you are using 2.1 try 2.0, or change 2.x to 2.0 explicitly to double check

Okay. Thanks. I'll give those options a try
