Invalid rule result: Instance of class Promise

I'd solved my problem. My angular/cli version is 7.0.7 but I was find the @schematics/[email protected] in package-lock.json. So, I run the "npm install @schematics/[email protected] --save-dev" command and solved my problem. Thank you for interested.

Run npm install @schematics/[email protected] --save-dev replace version with the same as your @angular/cli (in this scenario, 7.0.7)
