Testing Angular component with unsubscribe Error during cleanup of component

Question

I\'m testing a component which subscribe router params. Every test pass and everything works fine. But if I look in the console, I can see an error:

Error

Answer 1

For me what fixed this error was inside of my component's ngOnDestroy, I wrapped my store dispatch and my unsubscribe in a try catch.

ngOnDestroy(): void {
 try {
  this.store.dispatch(new foo.Bar(this.testThing()));
  if(this.fooBarSubscription) {
   this.fooBarSubscription.unsubscribe();
  }
 } catch (error) {
   this.store.dispatch(new foo.Bar(this.testThing()));
  }
}
