TypeError: tools.codex_app__send_message_to_thread is not a function

What version of the Codex App are you using (From “About Codex” dialog)?

What subscription do you have?

Pro

What platform is your computer?

windows + linux remote

What issue are you seeing?

I have attempted to send a status report to the source task 01a03b21-c07f-7713-864f-f29b10d74a6f, but the current session does not expose a cross-task messaging interface; the call result was:
TypeError: tools.codex_app__send_message_to_thread is not a function
Therefore, the message was not delivered. I will continue to conduct read-only discovery and subsequent deployment preparations via the shared GitOps repository; if the platform provides this interface or includes the task in the current collaboration tree, I will immediately resend the status.

What steps can reproduce the bug?

I don't know.Quite unstable.Reminder, server network down for a while and after it resume some functionality can be resumed.

What is the expected behavior?

No response

Additional information

No response

Start by reproducing the reported TypeError around tools.codex_app__send_message_to_thread, including after the server connection resumes, and trace where that interface is exposed. Done means the named tool is available in the affected session and successfully delivers a message; the issue provides no file or test path.
