Notes

1. API Key - Requires Alibaba Cloud Bailian platform account and API Key 2. Image Compression - Reference images are automatically compressed to meet API limits 3. Network Requirements - Requires access to Alibaba Cloud dashscope service 4. Synchronous Calls - qwen-image-2.0 uses synchronous calls, no async task waiting

Error Handling

Common errors and solutions:

| Error | Cause | Solution | |-------|-------|----------| | API Key error | Not configured or incorrect | Check .env file or environment variable | | Image too large | Reference image exceeds limit | Script auto-compresses, if still fails use smaller image | | Network error | Cannot access Alibaba Cloud | Check network connection |
