activating desktop client not working

[theresistance2]

Hey!

Install via umbrelOS app store went flawless, the app works awesome in browser too, but when following the tutorial to activate the desktop client, i cant get it to work:

Step 9: https://docs.solidtime.io/self-hosting/guides/docker

if i enter the command in the solidtime folder, i get this warnings and it fails:
`mbrel@umbrel:~/umbrel/app-data/solidtime$ docker compose exec scheduler php artisan passport:client --name=desktop --redirect_uri=solidtime://oauth/callback --public -n
