AttributeError: module 'demo' has no attribute 'app'

Hello,

I am trying to run the http3_server.py in my local machine, but I got this error:

application = getattr(module, attr_str)
AttributeError: module 'demo' has no attribute 'app'

I really have the server and demo script in my computer. What can I do to resolve this error?

Hope you didnt made any changes to your local aioquic project files

root@ubuntu:~/aioquic# python examples/http3_server.py --certificate tests/ssl_cert.pem --private-key tests/ssl_key.pem -v
Traceback (most recent call last):
File "examples/http3_server.py", line 562, in
application = getattr(module, attr_str)
AttributeError: module 'demo' has no attribute 'app'

Hope you are getting same above error .

if so make sure you have

async def app(scope: Scope, receive: Receive, send: Send) -> None:
if scope["type"] == "webtransport" and scope["path"] == "/wt":
await wt(scope, receive, send)
else:
await starlette(scope, receive, send)

in demo.py

Hope this helps
