Resolver Emitting Error ` ERROR Error: “[object Object]” `

Question

I\'m having a problem with regards of implementing a resolver on my routes as it has no issue until I include InitialDataResolver on my routing module.

Answer 1

This lack of detailed error occurred when using Mozilla Firefox. so what you need to do is to switch over to Google Chrome to see the specific error.

UPDATED:

You can also Store the error as Global Variable

then you can type temp0.message to see the actual error message

Answer 2

This error comes due to wrong router declaration. Also exact error never going to come in Firefox. Check route file in chrome. #angularjs-route

Answer 3

In console you can store errors like

ERROR Error: "[object Object]"

as global variable

and then get error message from object temp0.message

Answer 4

Mainly this error is found when using database object from '@angular/fire'

this can be fixed by using this.db.object('/' + ....).subscribe(...)

Answer 5

one-time solution : find function defaultErrorLogger in dist/vendor.bundle.js and add:

for (var _i = 1; _i < arguments.length; _i++) {
    values[_i - 1] = arguments[_i];
}
console.log(arguments);
console.error.apply(console, values); code here

then refresh page without recompiling

Answer 6

resolve(route: ActivatedRouteSnapshot,
      state: RouterStateSnapshot): Observable<any> {
    return Observable.create((observer: Observer<any>) => {

      this.appInitService.init()
          .subscribe(data => {
            this.appInitService.preload();
            observer.next(data);
            observer.complete();
          });

    }).map(item => !!item)
}

The code above will work for you.

if your rxjs version is 6.x you will use .pipe(map(item => !!item))
