Hey! I've removed the duplicate threads you created. We think there was a bug in the submission flow when you created the thread from your deployment crashed panel resulting in many duplicates. Sorry about that.

About your error, it looks like you're using a tech stack that isn't supported in Nixpacks (see https://nixpacks.com/docs/getting-started -> Language Support), so in order to build and deploy on Railway, you'll need to create a custom Dockerfile (https://docs.railway.app/reference/dockerfiles).
