Railway fails during build with this error:

[stage-0 7/9] RUN --mount=type=cache... npm ci
process "/bin/bash -ol pipefail -c npm ci" did not complete successfully: exit code: 1

I’ve already:

    Removed Dockerfile and nixpacks.toml

    Deleted node_modules and package-lock.json, reinstalled with npm install

    Pushed clean code with a valid package.json

    Set "start": "node server.js" in scripts

    Cleared Railway's build cache and redeployed
