Bug Report: Codex Sanbox Issue

`Steps to Reproduce`

Every terminal command now immediately fails with the Codex CLI error “unexpected argument '--sandbox-policy-cwd'.”

That means the CLI wrapper itself is broken—nothing gets executed (even ls)

`Expected Result`

Working CLI with shell commands and all tools enabled.

`Actual Result`

Every terminal command now immediately fails with the Codex CLI error “unexpected argument '--sandbox-policy-cwd'.”

That means the CLI wrapper itself is broken—nothing gets executed (even ls)

`Environment`

Windows 11 WSL Ubuntu

I can send my config.toml and wrapper

[dusky sigil]

@ebon dawn

[ebon dawn]

Run type codex and share results

Also run:
which codex
file codex

And post all 3 results

[dusky sigil]

codex is /home/beni/.npm-global/bin/codex

/home/beni/.npm-global/bin/codex

beni@BeniPC:~$ file codex
codex: cannot open `codex' (No such file or directory)

[dusky sigil]

Here;

[dusky sigil]

@ebon dawn it cant run any shell commands right now

And I cant work on my project like this

Should I send my config.toml

or wrapper

[ebon dawn]

Yeah share your wrapper

[ebon dawn]

Have you tried running codex without the wrapper?

[dusky sigil]

It happens with any mode I do

Running just codex too

[ebon dawn]

I would try cloning the openai/codex repo and building it from scratch, or doing npm i -g @openai/codex@0.55.0 use a specific version

[dusky sigil]

I need the latest version with everything enabled

Everything was working but this sandbox flag keeps coming up and ruins my shell commands

Unified_exec experimental true rmcp_client experimental true apply_patch_freeform beta true view_image_tool stable true web_search_request stable true experimental_sandbox_command_assessment experimental false ghost_commit experimental false enable_experimental_windows_sandbox experimental false

Even though sandboxing is set to false

[ebon dawn]

Try putting feature.unified_exec = false in your config and try again

That feature gives codex a reusable shell. When you turn it off it runs slower but it spawns a new shell every time codex runs a command on your computer so it’ll survive errors like that

[dusky sigil]

Error loading configuration: invalid type: map, expected a boolean
in features

[ebon dawn]

Gotcha. “features.unified_exec = false”

[dusky sigil]

Fixed

[dusky sigil]

Still no network access

Why?

Its turned on in the config

But still says no network access

[ebon dawn]

Share config, but erase any JWT tokens from it first
