Data path "" must NOT have additional properties(ngswConfigPath)

Question

I downloaded example from angular.io and followed the tour: https://angular.io/guide/service-worker-getting-started#cli-command

ng add @angular/pwa   
ng build

I faced this error:

Error: Schema validation failed with the following errors:
  Data path "" must NOT have additional properties(ngswConfigPath).
E:\Personal Project\service-worker-example\node_modules\rxjs\dist\cjs\internal\util\reportUnhandledError.js:13
            throw err;
            ^

SchemaValidationException [Error]: Schema validation failed with the following errors:

      keyword: 'additionalProperties',
      params: { additionalProperty: 'ngswConfigPath' },
      message: 'must NOT have additional properties'
    }
  ]
}

Please give me advice on this issue.

Thank you guys!

i was tried remove node_modules and reinstall but not working

I using angular v17

Answer 1

Remove the ngswConfigPath property. This must be an artifact of transitioning from the browser to application builder. Also remove this line "serviceWorker": true as it's invalid.
