Error: Error: Unexpected value 'undefined' declared by the module 'ComponentsModule', why?

Question

Angular

Good evening. Need help. For the second hour I have been struggling with a solution (Google did not help).
The above error is displayed.
Briefly about the code:

By the name of the error, I can assume that the ComponentsModule module declares the InputComponent component as undefined.
Code from the InputComponent file:

import { Component } from "@angular/core";
import { InputInnerComponent } from "./input-inner";

@Component({
  moduleId: module.id,
  selector: "input-comp",
  templateUrl: "input.component.html",
})
export class InputComponent {}

If you need any more files, please unsubscribe.
Thank you in advance.

Found what the problem is.
In case anyone has a similar error:
In the barrel file, I first exported all the components, and then the module.
It was necessary to export the module as the latest.
