TL;DR

The issue may be related to the Codex CLI version or compatibility with the terminal emulator, and checking the terminal emulator settings or updating the Codex CLI might help.

Guidance

  • Verify that the image error is not a one-time occurrence by retrying the prompt.
  • Check the VSCode terminal emulator settings to ensure that image rendering is enabled.
  • Consider updating the Codex CLI to a newer version, if available, to ensure compatibility with the latest features and fixes.
  • If the issue persists, try using a different terminal emulator to isolate the problem.

Notes

The provided information lacks specific details about the error message or the expected behavior, making it challenging to provide a more targeted solution.

Recommendation

Apply workaround: Try using a different terminal emulator to see if the issue is specific to VSCode, as this can help isolate the problem and potentially identify a compatibility issue.
