Additional information

It is the same behaviour as https://github.com/openai/codex/issues/17367, but in 0.123.0 it works well

It seems that the since switching to bubblewrap, the codex sandbox has been having frequent issues with the permissions.

extent analysis

TL;DR

The issue is likely due to a permissions problem with the Codex sandbox after switching to bubblewrap, and reverting the permissions configuration or checking the file path might resolve the issue.

Guidance

  • Check the file path /home/user/.npm-global/lib/node_modules/@openai/codex/node_modules/@openai/codex-linux-x64/vendor/x86_64-unknown-linux-musl/codex/codex to ensure it exists and is correctly referenced.
  • Verify that the default_permissions and permissions.workspace.filesystem settings in ~/.codex/config.toml are correctly configured and compatible with the current version of Codex CLI.
  • Compare the permissions configuration with the previous version (0.123.0) that worked well to identify potential changes that might be causing the issue.
  • Consider reverting to the previous version or adjusting the permissions configuration to match the working setup.

Notes

The issue seems to be related to a change in the Codex sandbox permissions after switching to bubblewrap, and the provided error message suggests a file not found error. However, without more information about the expected behavior, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Revert the permissions configuration to a previous working setup or adjust it to match the requirements of the current version, as the issue seems to be related to a change in the permissions configuration.
