Mounted WSGIMiddleware to "/" in fastapi

[jonathan-s]

My situation is the following. First I have an apirouter that has the path /my_path. After that I mount a WSGIMiddleware to "", ie it should match the root.

What then happens is that for any route I try that should reach the wsgi app I get a 404 that has the standard fastapi 404 error. If I reverse the order, mount the wsgi middleware first, and then add the fastapi routes the wsgi app works as expected, but the fastapi routes are swallowed by the *. regex that starlette defines for apps.

So the order should be first define fastapi routes, then the wsgi app, but I can't for the life of me understand why the routing doesn't reach the mounted wsgi app.

Is there a good way of resolving this?

Answering my own issue. I was using uvicorn.run with a string, and so used an app factory, in that app factory, the mount route was not included.
