Python error when running make start

Hi, I'm trying to deploy outline via docker following your repo and guide. I run git clone, cd, make install, insert all required vars, run make https, then I run make start. When I run make install, it triggers this error:

root@debian:~/outline-wiki-docker-compose$ make start
=> Open https://api.slack.com/apps and Create New App
=> After creating, scroll down to 'Add features and functionality' -> 'Permissions'
=> 'https://localhost/auth/slack.callback'
Copy the above to Redirect URLs. Press Enter to continue...
=> Save, go back and scroll down to 'App Credentials'
Enter App ID [(hidden)] :
Enter Client ID [(hidden)] :
Enter Client Secret [(hidden)]:
Enter Verification Token (*not* Signing Secret) [(hidden)]:
=>run 'make start' and your server should be ready shortly.

I already tried to update all system packages, deleted all docker containers, images and network (using prune) and outline local git clone folder, and reinstall outline (with and without make https) and still trigers this error.
