Angular 6 Error Handling not showing toasts
I am using the code below to catch errors in my small Angular 6 app... I am catching the errors, I am showing info in the console the problem is that the toasts do not show unless I click somewhere in the application, they don't show up all by themselves. I am using the ToastrService in other parts of the application and whenever I call it like I do it here it shows toats without having to click on anything.
Any idea what might be causing this behaviour?
import { Injectable, ErrorHandler, Injector } from '@angular/core';
import { Router } from '@angular/router';
import { HttpErrorResponse } from '@angular/common/http';
import { ToastrService } from 'ngx-toastr';
import { AppSettings } from '../../app.settings';
@Injectable()
export class GlobalErrorHandler implements ErrorHandler {
constructor(private injector: Injector) {}
public handleError(error: any) {
const router = this.injector.get(Router);
const settings = this.injector.get(AppSettings)
const toastr = this.injector.get(ToastrService);
console.log(`Request URL: ${router.url}`);
console.log(error);
if (error instanceof HttpErrorResponse) {
console.log("it is");
if (error.status === 401) {
router.navigate(['/login']);
settings.settings.setLoadingSpinner(false);
toastr.error('Logged in user no longer authenticated on server.', 'Unable to connect to server');
} else if (error.status === 404) {
console.log("it is 404");
toastr.error('Unable to connect to server. Missing or wrong URL, please try again', 'Unable to connect to server');
settings.settings.setLoadingSpinner(false);
} else if (error.status === 0) {
toastr.error('Server appears to be temporary unavailable', 'Unable to connect to server');
settings.settings.setLoadingSpinner(false);
} else if (error.status === 500) {
toastr.error('Server appears to be temporary unavailable', 'Unable to connect to server');
settings.settings.setLoadingSpinner(false);
}
} else {
console.error(error);
toastr.error('An error has occured', 'Sorry');
}
}
}
I have added the provider in the module also to use this class as error handler.

It would be great if you could provide a Minimal, Complete, and Verifiable example. You can use StackBlitz to create one.

please include the toaster service in constructor and run. As per my understanding, while service get instantiated, toaster should have to get initiated.
