Schema validation failed with the following errors:
Data path "" must have required property 'outputPath'.

Answer 1

I solved the problem. It was because of the name of builder in angular.json.

"serve": {
      "builder": "@angular-builders/custom-webpack:browser",
...
}

should be:

"builder": "@angular-builders/custom-webpack:dev-server",
