copyfiles command not found on AWS Amplify build

I know this is only

to Payload but hoping this group can help. 🙏🏻

As the title says, trying to get payloadcms/template-commerce deployed on AWS Amplify but keep running into an issue where copyfiles isn't found. My mongodb is on Mongo Atlas.

AWS Build Settings

version: 1
frontend:
  phases:
    preBuild:
      commands:
        - yarn install
    build:
      commands:
        - yarn run build
  artifacts:
    # IMPORTANT - Please verify your build output directory
    baseDirectory: /
    files:
      - '**/*'
      - 'dist/**/*'    # Add the 'dist' directory for the server code
      - 'build/**/*'   # Add the 'build' directory for the built admin panel
  cache:
    paths:
      - node_modules/**/*

AWS ENV Variables (not sure if important)

No help for this one?
