TypeError: string indices must be integers, not 'str' in ComfyUI better_combos.py

[fememystic]

I'm encountering an error while running ComfyUI, The error occurs in the better_combos.py script, specifically in the populate_items function at line 98:

names.sort(key=lambda i: i["content"].lower()) This line is trying to sort a list names using the lowercase of the "content" key as the sorting key for each element. However, it seems that the elements in the names list are strings, not dictionaries, causing the error TypeError: string indices must be integers, not 'str'.

This is what AI told me :D

I've tried to debug the issue, but I'm not sure how to resolve it. Can someone please guide me on how to fix this error? Is there an issue with the data structure being passed to the populate_items function, or is there a problem with the sorting logic itself?

Any help or suggestions would be greatly appreciated. I'm happy to provide additional information or context if needed.

Hi ! I'm having the same error. The strange thing is that yesterday everything was working normally and today when it loads I'm having this error:
