Parse Deploy Of Cloud Code Failing With Message "Update Failed With Internal Error"

I've been running Parse cloud code for a few months using CLI version 1.4.1 with no problems. I just updated using the CLI to the latest version, 1.4.2, but now when I deploy I get

Solution 1:

Upon upload attempt, Parse is parsing your code (pun intended :-) checking for errors, and deployment fails if any errors found.

One possibility is to check Logs (in your Dashboard under Core/Logs), also the Error submenu of Logs.

Another is to run the command parse develop your_app and see all the errors in your terminal.

For a large code, you probably want to write some unit tests if you aren't doing this already.
