Redirection with resolvers Angular 6

I use angular-cli for my application and I have a login page and here is the handler to submit it:



onSubmit() 
this.authService.login(this.uname.value, this.pass.value)
.subscribe(
(user: User) =>
this.username = user.username;
localStorage.userExist = true;
this.route.navigate(['/office/1']);
,
(err) =>
this.errorFromServer = err.error;
);



After submission, I expect that I would be redirected to localhost:3000/office/1, but instead, I get an error:



GET http://localhost:3000/api/plan net::ERR_CONNECTION_RESET.


http://localhost:3000/api/plan provides information about office plan and I get this data with help of PlanResolver. Actually, I can get this data when I switch between offices, but it doesn’t work when I try to redirect from login page. So, maybe, something wrong with navigation inside subscription.



I have two resolvers that should be executed before navigation:



path: 'office/:id', component: OfficesComponent,
resolve: cres: OfficeResolver, plan: PlanResolver,
canActivate: [AuthGuardService],


When I had one resolver, it worked fine, so I decided to combine two resolvers into one with forkJoin, but I got the same error.



The only one solution I have now is putting navigation in SetTimeout:



setTimeout(() => 
this.route.navigate(['/office/1']);
, 500);


If you have any ideas what is wrong please tell me.



Thanks all.

          .navigate method takes array of commands as a first argument. You are passing composed url like to .navigateByUrl. Thus resolver could not have access to id parameter.



          Try redefine redirection like this:



          this.route.navigate(['office', 1']);

          • Can you let me know why do you need to update this.username component property just before navigation? I mean it launch change detection cycle and it could explain why redirection works fine only after the process completion (in setTimeout callback. You can set it even to 0ms, fyi).
