#31984: Uvicorn + Django: TypeError: object HttpResponse can't be used in
'await'
expression
-----------------------------------------+-------------------------------
Reporter: aaronn | Owner: nobody
Type: Bug | Status: new

-----------------------------------------+-------------------------------
It seems like running Django with an asgi server like uvicorn in 3.1
causes `TypeError: object HttpResponse can't be used in 'await'
expression` to be raised. Runserver works fine, as does gunicorn + wsgi.
This is happening across two different projects for me.
