Hmm, haven’t seen this error recently.
However I have noticed one big change after updating recently, every night between 12:30am and 2:30am I will see a series of errors related to AI which are overloading the API rate limits.
I did not see these issues looking back through the logs to before the upgrade. Does discourse refresh the summaries or do other “refresh” work on every post on every night? We have a small forum with at most a few new posts a day. I don’t see any reason for Gemini rate limits to be exceeded every night at the same time unless it’s redoing everything for all historical posts.
