Angular 15 google chart application errors on build

Question

I have an application that works well under Angular 12. This application includes the use of google charts

It keeps erroring on the build.

To try to demonstrate the error I built a tutorial using only a very basic test. When I try to build this test application in Angular 15 I keep getting this message:

Error: app.component.html:4:6 - error TS2322: Type 'string' is not assignable to type 'ChartType'.

4     [type]="chartData.type"
       ~~~~

  app.component.ts:5:16
    5   templateUrl: './app.component.html',
                     ~~~~~~~~~~~~~~~~~~~~~~
    Error occurs in the template of component AppComponent.
