[ Impact ]
The package can't be used at all in its current state because it doesn't work with one of its central dependencies. It creates a backtrace as seen in the original bug description on simple usage cases.
The bugfix makes the package compatible with the newer version of the dependency.
[ Test Plan ]
See the example code in the bug description, but for convenience I paste it here again:
Create a file "fastapi-test.py" with the following code:
-----
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
async def root():
return {"Status": "ok"}
-----
Then run that file with python interpreter.
[ Where problems could occur ]
The package isn't usable at all right now. It can't get worse than that, frankly speaking.
