Unknown Flow Error

I'm getting an unknown error when a specific user is running flows: Null. I can't ffigure out what is causing this. The flow errow email doesn't event saying what element is causing the problem.

Any ideas?

"Error Occurred During Flow "XXX": null"

Are these the only elements in the flow and is that fast lookup inside your loop?  If so, nested loops might be a better way to go so you don't hit query limits.  I'm not seeing any outcome other than updating a counter, are you passing that off to something else or are you expecting something to happen?

Yes those are the only elements in the loop. The idea is to create a list of comments and display it in the next screen element after the loop.
The problem just happens at random and only for a specific user.
