NGXS doesn't work when update to Angular 9 with Ivy enabled

I'm trying to update my application to Angular 9. Everything runs fine when I disable the Ivy, but with Ivy enabled the application doesn't finish the serve task correctly:

My component:

choosePlan(plan: IPlan) {
  if (!this.isAddressValid()) {
    this._toastService.error('Informe o seu CEP!', '', { positionClass: 'toast-top-right' });
  } else {
    this._actions$
      .pipe(
        ofActionSuccessful(this.addItem(plan)),
        tap(() => this._clearUtms())
      )
      .subscribe(() => this._router.navigate([`/checkout/carrinho/${this.cart.id}`]));
  }
}

My state:

@State<CartStateModel>({
  name: 'cart',
  defaults: {
    cart: {},
  },
})
@Injectable()
export class CartState {
  @Action(Cart.AddItem)
  addItem(ctx: StateContext<CartStateModel>, action: Cart.AddItem): Observable<ICart> {
    const currentState = ctx.getState();

    return zip(this.address$, this.shipping$).pipe(
      mergeMap((obs: [IAddress, IShippingType]) =>
        this._cartService.addItemToCart(
          currentState.cart.id,
          action.itemToAdd,
          obs[0].cep,
          obs[1].shippingMethodId
        )
      ),
      tap((cart: ICart) => ctx.setState({ cart: cart })),
      take(1),
      catchError((error: any) => throwError(error))
    );
  }
}

My action:

export class Create {
  static readonly type = '[Cart] Create';
  constructor(public itemToAdd: ICartItemToAdd) {}
}

The error of VS Code from Typescript: Here the image: error from typescript code

  Type 'AddItem' is not assignable to type 'ActionType'.
    Property 'type' is missing in type 'AddItem' but required in type '{ type: string; }'.

The error is about the type of Action:

export namespace Cart {
  export class Create {
    static readonly type = '[Cart] Create';
    constructor(public itemToAdd: ICartItemToAdd) {}
  }
}

One of these errors is gone when I remove the line:

static readonly type = '[Cart] Create';

But I can't, because the Actions need a type.
