Build failed after updating to Ionic 5

Ionic Framework Ionic Angular
1

I have just updated my app to Angular 9 and Ionic 5, but whenever I try to build the app I get the following error.

I have tried deleting platforms and node modules, as well as running ng update and npm outdated.

npm install of external dependencies ok

ng run app:ionic-cordova-build --platform=ios
Schema validation failed with the following errors:
Data path “.scripts[0]” should NOT have additional properties(lazy).
Data path “.scripts[0]” should be string.
Data path “.scripts[0]” should match exactly one schema in oneOf.
[ERROR] An error occurred while running subprocess ng.

On angular.json file if you habe an empty script tag, like this, Just remove it !

 "build": {
      "options": {
       ....,
       "scripts": []      <-- Remove this line
