I am new to angular and Ionic. I am using
"@angular/forms": "^4.3.1" "ionic-angular": "^3.5.3"
I have installed the ionic-angular and @angular/forms package. I am getting the following error message.

Unhandled Promise rejection: Template parse errors:
'ion-card-header' is not a known element:
1. If 'ion-card-header' is an Angular component, then verify that it is part of this module.
2. If 'ion-card-header' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("

      <ion-card>
        [ERROR ->]<ion-card-header>
          Header
        </ion-card-header>

any thought how to fix will be really appreciated.

I was able to fix this issue by disabling the angular ivy complier, in tsconfig.app.json

"angularCompilerOptions": {
    "enableIvy": false 
},
