Debugging

If you encounter any issues:

1. Check that all dependencies are installed correctly
2. Verify that the server is running and listening for connections
3. For local image loading issues, ensure the file paths are correct and accessible
4. For "Unsupported image type" errors, verify the content type handling
5. Look for any error messages in the server output
