Question

I am having trouble building on Amplify hosting using custom build scripts in amplify.yml. The script always gets hung up on whatever command I use before amplify pull. I need pull to bring in the aws-exports.js file and a post-pull script to run in order to modify that file. I have not even been able to get pull to run in the build process. Here is an example of the yml in one attempt:

version: 5
backend:
  phases:
    preBuild:
      commands:
        - npm config set //registry.npmjs.org/:_authToken=${NPM_AUTH_TOKEN}
        - echo "@pqina:registry=https://npm.pqina.nl/" >> .npmrc
        - echo "//npm.pqina.nl/:_authToken=${PQINA_NPM_TOKEN}" >> .npmrc
        - npm i
    build:
      commands:
        - echo "running build backend..."
        - amplify pull --appId ddkfcre2qrht6 --envName test --yes
        - echo "hello"
frontend:
  phases:
    build:
      commands:
        - npm run build
  artifacts:
    baseDirectory: .next
    files:
      - '**/*'
  cache:
    paths:
      - node_modules/**/*
