I see the below sequence of errors continuously while summarizing a codebase, I see the same issue when I use codex standalone or within Cursor.

Is this still happening?

Yes, still see the issue, tried it just now at 11.20AM EST, below is console output, thank you.
p.s. happened to stop the session with ^C, hence the last message/2-lines from codex unrelated to the current issue.

We are prioritizing looking into this. I will mark as duplicate here because there are a few other reports, but we are actively working on resolving these issues.
