'Unable to import type Date' in Input transform

[hisham]

🐞 bug report

Is this a regression?

No

Description

I'm implementing an Input transform that converts a string to Date, but the angular vscode extension is not accepting type of 'string | Date' for the input value.

The error I get is: Unable to import type Date. The symbol is not exported from /Users/<username>/.vscode/extensions/angular.ng-template-17.0.2/node_modules/typescript/lib/lib.es5.d.ts.(-993004) lib.es5.d.ts(22, 3): The type is declared here.

Bug Type

What does this bug affect

• Angular Language Service VSCode extension
• Angular Language Service server

Reproduction

function dateAttribute(value: string | Date): Date {
  return typeof value === 'string' ? new Date(value) : value;
}


@Component({
  selector: 'foo-bar',
  standalone: true,
  imports: [CommonModule],
  templateUrl: './foo-bar.component.html',
  styleUrls: ['./foo-bar.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush,
})

  @Input({
    transform: dateAttribute,
  })
  pausedAt: Date;
