📄 Description

First off, thanks for this summarizer filter! It's been very helpful.

However, I'll occasionally start getting the error, “Summarizer error: 'list' object has no attribute 'split'“. It looks like the message content is sometimes of type list.

Digging around in the backend, I see places like this that show message content can be a list of dictionaries: https://github.com/open-webui/open-webui/blob/main/backend/open_webui/utils/payload.py#L249

I plugged this change into my OWUI instance, and it's working. It also fixed a session that was stuck on the summarizer error.
