"I swear it works on my machine" Railway edition

Question

Railway doesn't seem to be able to build my latest commit, I moved to using Railpack once announced but trying to fix the problem I got back to good old docker and it still works fine locally but not on railway, is there a way to check railway build files to ensure that the module is still there or something like that?

Dockerfile:

FROM node:22-slim

WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install

COPY . .

RUN npm run build

ENV NODE_ENV=production

CMD ["npm", "run", "prod"]

Dockerfile:
```Dockerfile
