Angular 13 forms module related errors with forms module installed

Question

notice:

Error: src/app/money_makers/shochat_guts/shochat_content_creator_components/active-stream-dashboard/shochat-contentcreator-chat/shochat-contentcreator-chat.component.html:81:18 - error NG8002: Can't bind to 'ngModel' since it isn't a known property of 'input'.

81                  [(ngModel)]="forminput"

but look at my app module

import {FormsModule} from '@angular/forms';

    imports: [
    FormsModule,
    ....
    ]

this error only happened when I migrated my angular 10 project to a angular 13 project.

I did this migration by starting a new angular 13 project and then moving over the src folder to the new angular 13 project and then installed all dependencies

why is this happening?

  declarations: [
    ...

Answer 1

Make sure you also import the FormsModule in the feature module which holds the component where you are using the ngModel.

@NgModule({
  imports: [FormsModule], 
  declarations:[ShowChatComponent] 
})
export class ShowChatModule {}
