Description

Hello, I got that message immediately after I clicked Generate button. This error i got after update. I hope the author can fix this. Thank you.

Traceback (most recent call last):
File "E:\webui_forge_cu121_torch21\webui\modules\call_queue.py", line 74, in f
res = list(func(*args, **kwargs))
TypeError: 'NoneType' object is not iterable

Research direction

Start by reproducing the failure with the Generate button after the reported update, then inspect modules/call_queue.py around line 74, where the result is passed to list(). Trace the Generate call to determine which function returns None instead of an iterable; done means identifying the regression and confirming generation completes without this TypeError.
