Docker image doesn't start since recent changes.

[TheNamelessWonderer]

Describe the bug
Since the recent changes to git I assume it is #825. The docker image doesn't start anymore. This also applies to the docker image at ghcr.io/matrix-org/matrix-appservice-discord:develop

To Reproduce
Steps to reproduce the behavior:

1. Compile the docker image or use ghcr.io/matrix-org/matrix-appservice-discord:develop
2. Start the image
3. Check logs
4. See error

Expected behavior
The Docker image should start without any errors.
