what version of Sanic are you using?

[g1i1U]

Name: sanic Version: 18.12.0
Python 3.9.10

We need to correct the dependencies. IDOM requires sanic>=19,<19.12 which, admittedly, is a rather slim range of versions. This is because of this issue.

I'd suggest using a different server implementation if you need more flexibility here (e.g. FastAPI or Starlette) - see docs for more info on using alternate server types.

Here's an issue which will track the dependency update: #678
