codex exec resume --last rejects prompt when --json is set

[dkhokhlov]

What version of Codex is running?

0.58.0

What subscription do you have?

team

Which model were you using?

gpt-5 codex

What platform is your computer?

Linux 6.2.0-39-generic x86_64 x86_64

What issue are you seeing?

Running the exec CLI with both --json and resume --last fails whenever a prompt is provided after --last. Clap treats that positional as SESSION_ID, so it errors with “the argument '--last' cannot be used with '[SESSION_ID]'”.

Execution aborts immediately with error: the argument '--last' cannot be used with '[SESSION_ID]'.

What steps can reproduce the bug?

Run:
codex exec --json resume --last "2+2"

What is the expected behavior?

The command resumes the most recent session and sends "2+2" as the new prompt while still emitting JSON events.

EDIT . Actually exec version (non interactive) works . Interactive doesn't. Not sure if I should create separate ticket.

On latest version 0.63 you still cannot use it . For command :
codex resume --last "tell me the same joke"

I get

error: the argument '--last' cannot be used with '[SESSION_ID]'

Usage: codex resume --last [SESSION_ID] [PROMPT]
