Codex suddenly started to view the image and crashed the session, even I did not say anything about or related to the image.
• Ran python - << 'PY'
│ import pathlib
│ p = pathlib.Path('app')
• Explored
└ Search \[id\]\.tsx in app
• Viewed Image
└ app/(modals)/intro/[id].tsx
■ unexpected status 400 Bad Request: {
"error": {
"message": "Invalid 'input[37].content[0].image_url'. Expected a base64-encoded data URL with an image MIME type (e.g. 'data:image/png;base64,aW1nIGJ5dGVzIGhlcmU='), but got unsupported MIME type 'image'.",
"type": "invalid_request_error",
}
}
And this issue cannot be recover even I try to skip this step
