Problem updating to 3.0.5

[ssweber]

After updating to 3.0.5 (or 3.0.6) I get the following response on all chats:

'NoneType' object has no attribute 'get'

I looked at the updating log, and the only issue I saw was this:

Anyone else have a problem?

Ignore the log error. That looked to be present in 3.0.4 as well.

[ssweber]

Hmm. Re-upgraded to 3.0.5 and it's working. I'll update to 3.0.6 and see if it's still working

[ssweber]

Consider this closed. I did get the error again, but then I read I should turn embedding engine on and off.

I had the “ Bypass Embedding and Retrieval” On. I turned it off. And that seemed to have fixed the problem.

See https://docs.openwebui.com/troubleshooting/rag/

“
Go to: Admin Settings > Documents > Embedding Model
Save the embedding model again—even if it's already selected. This forces a recheck/download.

Hello @ssweber
Thanks for reporting and keeping a detailed log on your solution finding process.
This helps future readers and is much appreciated.

As it turns out, that wasn't really the fix.

With each new 'page load', the same things happens. But if I reload the same conversation after visiting like the admin page, and resend the chat, then it works.

Maybe next week I'll have time to debug and create an issue on their github
