If a user changed or removed the session file, chat won't work next time.

The workaround is:

(setq ellama--active-sessions (make-hash-table :test #'equal)
      ellama--current-session-id nil)

@hwiorn Thank you. I will think how to fix it automatically in runtime.

[mberrueta]

In my case I didn't modified or deleted any file. and even if I exec

(setq ellama--active-sessions (make-hash-table :test #'equal)
      ellama--current-session-id nil)

the issue still persist

[s-kostyaev]

@mberrueta very strange. Could you please share your full ellama configuration (with replaced keys)?
