Answer 1

I ran into the same error today. You should downgrade your typescript dependency to 3.9.7. That fixed it for me.

Answer 2

Since downgrading a major language version was not really an option for me, and I by coincidence had a repository with an angular app that did not have the problem, I compared them to find this solution:

The error existed with @angular/… version 10.0.5. When I upgraded these packages to version 10.2.0, the problem was gone.

The full list for my basic app is below, but you might have more @angular/ prefixed packages:

    "@angular/animations": "^10.2.0",
    "@angular/common": "^10.2.0",
    "@angular/compiler": "^10.2.0",
    "@angular/core": "^10.2.0",
    "@angular/forms": "^10.2.0",
    "@angular/platform-browser": "^10.2.0",
    "@angular/platform-browser-dynamic": "^10.2.0",
    "@angular/router": "^10.2.0"
