GitAuto: describe_image encountered an BadRequestError: Error code: 400 - {'error': {'message': "You uploa...

[gitauto-ai]

Resolves #451

Why the bug occurs

The describe_image function attempts to upload unsupported image formats, such as SVG files, resulting in a BadRequestError with error code 400. This occurs because the API only accepts specific formats like PNG, JPEG, GIF, and WEBP.

How to reproduce

1. Use the describe_image function to upload an SVG file.
2. The function raises a BadRequestError indicating an unsupported image format.

Where / How to code and why

Modify services/openai/instructions/describe_image.py to include validation for image formats before uploading. Implement the following steps:

1. Validate Image Format: Check if the uploaded image is in one of the supported formats (png, jpeg, gif, webp). If it's an unsupported format like svg, proceed to the next step.
2. Convert Unsupported Formats: Use the Pillow library to convert unsupported image formats (e.g., SVG) to a supported format such as PNG.
3. Handle Conversion Errors: Implement error handling to manage any issues that arise during the conversion process, ensuring that meaningful error messages are logged and returned.
4. Update Dependencies: Ensure that the Pillow library is included in requirements.txt to handle image processing.

This approach ensures that all images uploaded through the describe_image function are in supported formats, thereby preventing BadRequestError instances and improving the robustness of the application.
