bug: codex "cannot parse json" and "cannot iterate over a consumed stream" errors

What version of Codex is running?

0.1.2504221401

Which model were you using?

o4-mini

What platform is your computer?

darwin | arm64 | 24.5.0

What steps can reproduce the bug?

Repro Steps

• Start codex cli codex
• Type in anything at all (full messages, to just "hi" with no spaces or other chars)
• Press enter

Variant

• Typing any slash command DOES work

What is the expected behavior?

In my first attempts I was giving directions to provide context and would have expected that I would get a reply telling me to that in some form. Later I was just typing "hello" or "hi" and would have just expected one of the canned responses about "I'm here to help" or whatever.

What do you see instead?

Minified error outputs. The 1 I captured is below and has an error from the subject of this issue in it. I also included a bit above so that you can see the prompt and that I had just cleared it in case any artifacts were causing the issue. Hope it helps 😄

Additional information

I also found the session file for the command above. You can see the invalid command thing when I typed /c and <tab> for completion on the clear command. I still see the issue when I don't use completion however.
