I am getting this error while running my application. Here are the details of my application.
Angular CLI: 7.3.3
Node: 10.15.1
Angular: 7.2.7
@angular-devkit/architect -0.13.3

@schematics/angular -7.3.3

I have already tried cache clean.
In your package.json change the devkit builder.
"@angular-devkit/build-angular": "^0.800.1",
to
"@angular-devkit/build-angular": "^0.10.0",
it works for me.
good luck.
