Description
What version of the Codex App are you using (From “About Codex” dialog)?
26.818.32112
What subscription do you have?
use openai api
What platform is your computer?
Microsoft Windows NT 10.0.22635.0 x64
What issue are you seeing?
Using OpenAI API to access Codex ++, the dialogue will now report this error every once in a while, resulting in the whole dialogue not being able to be used normally.
A new dialogue must be opened, but this error will also occur after a while in the new dialogue, which will make it impossible to use normally.
error example：
Invalid 'input[107].id': 'fc_08d2f9b0333b7690016a88ed74f82c87d0aa6bf2edc704ebc0'. Expected an ID that begins with 'ctc'. [trace_id=76843951e11a52345eaa4b2aba010e12]
What steps can reproduce the bug?
This error occurs frequently in long sessions, but it can take a long time to open a new session.
Once this error occurs, it cannot continue and a new session must be opened.
What is the expected behavior?

Research direction
Start by reproducing the failure during a long Codex App session on Windows using the OpenAI API, then trace the history replay path that sends the invalid input ID. Done means an existing session can continue after history replay without rejecting an ID that begins with fc_.
