Angular: 7.2.1 ES6 class ReferenceError : Cannot access 'X' before initialization

Question

I\'m having the following TypeScript class

export class Vehicule extends TrackableEntity {
  vehiculeId: number;
  constructor() {
    super();
    return s         


        

Answer 1

I was getting this error due to a circular dependency, like

• A injected with B
• B injected with C
• C injected with A

Removing the circular dependecy fixed this error.
