Identifier 'required' is not defined. '__type' does not contain such a member

There is a bug in angular. That compiler error will dissapear if you write that *ngIf like this:

          <div *ngIf="price.errors['required']">

angular typescript angularfire2

try to add "?" after "price".

Like this:

<div *ngIf="price?.errors.required">Price is required.</div><div *ngIf="price?.errors.min">Price should be 0 or higher.</div>

angular typescript angularfire2

I had same problem with my VS Code. I solved it only using !! before the condition.

Try:

<div *ngIf="!!price.errors.required">Price is required.</div><div *ngIf="!!price.errors.min">Price should be 0 or higher.</div>
