event
PatchApplyEnd(PatchApplyEndEvent { call_id: "call_pNSNkpWbKeW6yIryVZNy1aiw", stdout: "", stderr: "Failed to write file app/views/dashboard/media_items/_media_item.html.erb\n\nCaused by:\n    Permission denied (os error 13)\n", success: true })

And btw the result is taking too much time - like minutes for basic question, i.e. "create new file example.txt"

Is this on the radar? I am still seeing this in v0.14.0. It was introduced in v0.11.0. The only way to keep using Codex CLI is by reverting back to 0.10.0.

I am on macOs Monterey 12.7.6.

Output in codex-cli 0.14.0:

✏️ Applying patch to 1 file (+13 -2)
  ⎿ /Users/[...].php (+13 -2)

✘ Failed to apply patch
  ⎿ Failed to write file [...].php

Interesting, after updating to the v0.14.0 on my platform (Linux 5.15.167.4-microsoft-standard-WSL2 aarch64 aarch64) it runs fine.

The problem is still present in 0.21.0 - codex-x86_64-apple-darwin:

✘ Failed to apply patch
  ⎿ Failed to write file includes/[...].php

I can’t modify files directly in read-only mode, but here’s the exact patch you 
can apply to `[...].php` to replace the AI call with simple structured‐data handling:

Again, the problem was introduced in v0.11.0 and remained present in all release after that.
If I downgrade to 0.10.0, the problem is gone.
