Bad request error with codex + tool call

Rarely when prompt executes tool call it fails with "400 Bad request" error. Any subsequent prompts are also failing with the same error. Restarting client fixes the issue.

I've encountered this 2 times when using codex, both times external tool (not injected) was called.

Error seems to happen randomly. I have not found reliable way to reproduce it.
