I want to deploy ComfyUI on a service platform implemented with fastapi and expose ComfyUI’s front-end routes to the service platform. However, since ComfyUI is implemented with aiohttp, I want to know how to mount aiohttp’s routes to fastapi and access them normally.

I have tried to use a2wsgi.WSGIMiddleware to convert aiohttp app to ASGI and then mount to fastapi, but there are some bugs such as

uvicorn.error - ERROR - Exception in ASGI application

It’s the first time I write web code, and never used fastapi or aiohttp before, so this may be an available way, but I don’t write correctly.

I hope someone can help me or give me some suggestions.
