Error: oops ! something went wrong, please try again / reload. [stacktrace in console]

[outlogic]

I get the following error in WebUI:
"oops ! something went wrong, please try again / reload. [stacktrace in console]"

Reloading the page doesn't work.

The terminal shows the following;
"Using g4f.Provider.Providers.ChatgptAi provider
