Appveyor not running the build script

Question

Hello my build script isn't creating a build script for reason I do not know, the Packjson has the correct script which is

 "build": "npm run silentrenew && react-scripts --max_old_space_size=8192 build",

I have double checked my YML file and all the tags

version: '1.0.{build}'
image: Ubuntu
init:
  - cmd: set NODE_OPTIONS=--max-old-space-size=8192
environment:
  REACT_APP_VSA_URL: >-
    https://xzc-e-n-vsa0000-d-api-02.xzc-e-n-snt-06-ut-ase-01.p.azurewebsites.net

      # upload results to AppVeyor

      $wc = New-Object 'System.Net.WebClient'

      $wc.UploadFile("https://ci.appveyor.com/api/testresults/junit/$($env:APPVEYOR_JOB_ID)",
      (Resolve-Path .\coverage\junit\junit.xml))

      # upload coverage results to CodeCov

      $env:PATH = 'C:\msys64\usr\bin;' + $env:PATH

      Invoke-WebRequest -Uri 'https://codecov.io/bash' -OutFile codecov.sh

      bash codecov.sh -s "./coverage/jest/"

This is the exact message I'm getting in AppVeyor, since the build isn't creating it isn't running the test and saying it was successful.

For Linux builds the prefix must be sh: or no prefix at all:

build_script:
  - sh: |-
      npm --no-git-tag-version version "$APPVEYOR_BUILD_VERSION"
      npm run build
