Agent mode connected to Github repo almost always fails (after 10 mins of analysis)...why?

I am getting this message very often when I ask a Agent mode question in the web interface ChatGPT.

About 75% of the time, the Agent mode prompt eventually fails with this: getNodeByIdOrMessageId - no node found by id: 68b6e69e-eb94-492e-84c8-d3f1240a07e4
Or “sorry something went wrong”.

My Github is connected fine, the Agent can see it, I can see it working and analyzing files in there. The failure is after 10 minutes or so.

I lost about 10+ Agent credits (I have a Plus a/c). I’ve lost so many Agent and Deep Research credits through the session crashing!
