What does collectResults_ do?

I am running a script that does a job for me all night, and I wake up to this error. What is collectResults_ and what would be the cause of this error?

Traceback (most recent call last):
File “GlyphsApp/GlyphsApp/init.py”, line 3608, in collectResults_

AttributeError: ‘NoneType’ object has no attribute ‘length’

This is a callback to get errors from export operations. I add added a check to prevent the problem.

Yes, I am exporting several thousands of fonts at night. Is it because I am doing too many? It does seem to stop completely at one point.

There might be some memory leaks in the python bridge an after running for a long time, the Mac tunes out of memory. Can you send me the script and the source files that I can debug this?


I didn’t see you email, yet. Can you send it again?

It was sent to gs@yourdomaindotcom as WeTransfer link. It might have gone to your spam folder. I can re-send it if you can’t find it.

Found it.
