Codex dead ends when trying to View an SVG

What version of Codex is running?

codex-cli 0.63.0

What subscription do you have?

Plus

Which model were you using?

gpt-5.1-codex-max

What platform is your computer?

Darwin 25.1.0 arm64 arm (macOS tahoe)

What issue are you seeing?

Codex is making a tool call to try to view an SVG image, but fails with the error:

• Viewed Image
  └ island.svg

unexpected status 400 Bad Request: {
  "error": {
    "message": "The image data you provided does not represent a valid image. Please check your input and try again with one of the
supported image formats: ['image/jpeg', 'image/png', 'image/gif', 'image/webp'].",
    "type": "invalid_request_error",
    "param": "input",
    "code": "invalid_value"
  }
}

Once this happens, it is unrecoverable, as far as I can tell. Codex always retries this request when resuming after I type a new prompt, leading to the same dead end. This unfortunately provides me with no alternative but to discard my context and start a brand new session.

What steps can reproduce the bug?

Uploaded thread: 019adb6c-e720-7610-bbf7-3d27a7ea88f7

What is the expected behavior?

Either add support for viewing SVG image formats or prevent codex from attempting to view them which will always fail.
