Brody•11mo ago

the start script in your package.json but yes

lasseOP•11mo ago

Yes alr thanks for the help! @Brody ~~So i dont why its still not showing up. I have added the PORT as env variable. And updated the start command.~~ its fixed

Brody•11mo ago

lasseOP•11mo ago

Just needed to set the start cmd correctly too npx prisma genarate && npm run start and it was without Dockerfile.
