AttributeError: async

[albanm]

After your recent fix of mongodb config (thanks !), I have another error. Just to be clear I used "docker-compose down" to remove containers, images, and volumes, so I don't have any remnants of the previous versions.

After "docker-compose up -d" localhost:7000 responds with a 500 error. The logs of the container are saturated with a loop of messages containing a stack trace. Here is a full iteration of the loop:

Hi,

This is due to a faulty peer dependency, namely kombu. As a quickfix, you can run pip install kombu==4.1.0 in your container, or pin it in requirements.pip.

[albanm]

Thanks !

I also added the line for urllib3 and it seems to be working.

[abulte]

👍 sorry for the inconvenience, you seem to have joined the project at a time where our peer dependencies are going insane...

[albanm]

No problem ! Maybe using this would be a good idea : https://github.com/pypa/pipfile

The lock file is a nice feature.

[abulte]

Yes, we'll be looking into it 👍
