I managed to get the application started using these commands instead:

1. pnpm install
2. pnpm prisma db push after I have added environment variable DATABASE_URL
3. pnpm run dev

But when following the setup-wizard to create the first user I get this error:

[cmintey]

Instead of pnpm prisma db push, try pnpm prisma migrate dev

[cmintey]

Also if you'd like to implement any features, please add a comment to any existing (or create a new) feature request so I know and don't work on it as well.

[albinmedoc]

Still getting the last error when following the setup wizard, user already exist...

[cmintey]

Delete the db and run the prisma migrate dev. If it doesn't automatically run the seed command, then run pnpm prisma db seed as well

[albinmedoc]

Yeah, I got it working. Thanks!
