Describe the bug

I've been trying to setup a custom repository for a monorepo that will have several apps hosted on it.

The objective is to be able to share the backend with multple web and mobile apps.

I cant seem to be able to build the backend.

I get the following error within the console when attempting to build it.

BUILD.txt

this is the current repo

https://github.com/KinuQ/kinuqmono

Im honestly not sure what is it that I'm doing wrong.

I had another single repo app with a full fledged backend, and it is able to just go ahead and get deployed without an issue.

this is my amplify.yml for the CI process

version: 1
backend:
  phases:
    preBuild:
      commands:
        - corepack enable
        - pnpm install
    build:
      commands:
        - echo $AWS_BRANCH 
        - echo $AWS_APP_ID
        - pwd
        - cd packages/amplify
        - pwd
        - pnpm exec ampx pipeline-deploy --branch $AWS_BRANCH --app-id $AWS_APP_ID
        - cd ...
        
frontend:
  phases:
    build:
      commands:
        - pnpm turbo build
  artifacts:
    baseDirectory: apps/placeholderapp/dist
    files:
      - "**/*"
  cache:
    paths:
      - node_modules/**/*

Reproduction steps

attempt to deploy on aws.
