I think it's too complicated to analyze the workflow of comfyui

The error shows invalid characters in URL query parameters when fetching generated images. Look at the aiohttp server code handling GET /view requests, likely in the ComfyUI web server. Check how filenames with non-ASCII characters (like Chinese) are encoded in the query string. The fix involves proper URL encoding of the filename parameter before constructing the request.
