I got the same error. Looking for an answer.

[jxf1002]

I found a reason which is the version of sanic doesn't match requirements, and try to install sanic 19.9.0 fix this error.
pip install sanic==19.9.0

[Naktibalda]

@jxf1002 thanks for instructions how to fix it.

[sara-tagger]

Thanks for raising this issue, @akelad will get back to you about it soon✨

Please also check out the docs and the forum in case your issue was raised there too 🤗

[erohmensing]

From duplicate issue:

The latest version of Sanic v19.12.0 has introduced breaking changes and has broken the rest input channel. Please change the dependency for sanic back to 19.9.0.

[erohmensing]

@jxf1002 @Naktibalda can you confirm that it was v19.12.0 that introduced the breaking changes? does pip install sanic==19.11.0 work okay?

[rabinpoudyal]

ya for me too sanic worked but the regular setup did not work.

[YesayaSoftware]

I found a reason which is the version of sanic doesn't match requirements, and try to install sonic 19.9.0 fix this error.
pip install sanic==19.9.0

Thanks worked for me after a week of searching.

[jxf1002]

Oh, weird 🤔 perfect, we'll pinn 19.9.0, thanks for the help 👍

[persisty]

pip install sanic==19.9.0

Yes, this works. Thank you

[grootstebozewolf]

Still does not work with sanic version 19.12.2, work around fixed it.

[erohmensing]

This version should be correctly pinned in rasa 1.6.1. 👍
