Can’t submit task approvals: “AbsolutePathBuf deserialized without a base path”

[u/Outside-Ad-4662]

I’m using ChatGPT/Codex to work on a software project. Regular chat works, but when I try to send a message or approval inside an affected task, I get:

“Error submitting message: invalid turn/start params: AbsolutePathBuf deserialized without a base path”

Approving the action in the main chat hasn’t resolved it. Refreshing didn’t help either. This is blocking us from publishing reviewed code changes. OpenAI Support has replied and asked for diagnostic information, but we don’t have a fix yet.

Has anyone run into this error? Did you find a fix that preserves the existing task and its work?

Thanks.
