What happened?

We have a ticket showing new Sanic versions which are compatible with pyproject.toml breaking rasa-sdk. In addition to that, I find we have other incompatibilities with rasa. Currently we have sanic = "^21.6.0" in pyproject.toml file. In pypi we don't use lock files, poetry.lock file is for local dev only. If I update requirements and run shell, I get import error on CompositionView.

poetry update

Results in Sanic being upgraded to 21.12.0 from 21.9.3. When I run shell, I get following exception (app name exception should come later):

$ rasa shell --help
Traceback (most recent call last):
  File "/Users/tayfun/.virtualenvs/rasa3.0/bin/rasa", line 2, in <module>

    from sanic.views import CompositionView
ImportError: cannot import name 'CompositionView' from 'sanic.views' (/Users/tayfun/.virtualenvs/rasa3.0/lib/python3.8/site-packages/sanic/views.py)

Once https://github.com/RasaHQ/rasa/pull/10590/files is merged, check shell run again and see if Sanic name should be updated to be without any dots. After fixing Sanic app name, we should also check any other incompatibilities. If too many, we can also pin down Sanic in pyproject, but this has to be consistent with rasa-sdk.

This is potentially a duplicate of #10585

I just saw this bug re-appear on Rasa Open Source 3.0.5, despite the suggested fix in #10590.

We forgot to backport to 3.0.x :D here's PR for it https://github.com/RasaHQ/rasa/pull/10762/files
