Error Creating Task

Can you provide more details? It look like you're running the extension, but you've provided the version number for the CLI. Which platform are you using? Do you have any non-default configuration settings in codex.toml?

Do you see this as soon as you create a new thread, or does it occur only after you enter a prompt?

I am in vs code codex extension!
It happens after i start a old task

Can you please answer my other questions above? Which platform are you using? Do you have any non-default configuration settings in codex.toml?

No other custom config in codex.toml

It works again in a new thread. But that meant the work was only half done... Limits had not yet been reached either.

Same/similar issue, i get:- "Error creating task timeout", when sending a prompt in an old chat. It doesn't happen in new ones.

I got the same issue using vscode codex extension in wsl2, "Error creating task timeout"
