Question

An unhandled promise rejection occurred because no routes could be found to match. URL Segment:

I'm facing an issue with my application where it doesn't recognize the route even though I have defined and imported it in app.module.

Whenever I try to redirect to a specific route upon data retrieval, I encounter this exception:

onSubmit(){
    this.transactionService.createTransactionIfNotExist(this.video).subscribe(
      transaction => this.router.navigate([transaction.currentStep.action, this.video.id, transaction.token ]));
  }

transaction.currentStep.action = PreviewStep
this.video.id = 1
transaction.token = f54db125-ca01-4afc-b714-76c127abb261

The exception message is:

Uncaught (in promise): Error: Cannot match any routes. URL Segment: 'PreviewStep/1/f54db125-ca01-4afc-b714-76c127abb261'
Error: Cannot match any routes. URL Segment: 'PreviewStep/1/f54db125-ca01-4afc-b714-76c127abb261'

transaction.routing

export const routing: ModuleWithProviders = RouterModule.forChild([
   { path: 'previewStep/:videoId/:transactionId', component: PreviewStepComponent }
]);

transaction.module

import { PreviewStepComponent } from "./components/preview-step/preview-step.component";
import { routing } from './transaction.routing';

@NgModule({
  imports: [
    CommonModule, routing, FormsModule, SharedModule, RouterModule
  ],
  declarations: [PreviewStepComponent],
  providers: []
})
export class TransactionModule { }

app.module

import { AppRoutingModule } from './app-routing.module';
import { TransactionModule } from './transaction/transaction.module';

@NgModule({
  declarations: [
  ],
  imports: [
    AppRoutingModule,
    TransactionModule,
    BrowserModule.withServerTransition({ appId: 'ng-cli-universal' }),
    HttpModule,
    HttpClientModule,
    FormsModule
  ],
  providers: [ ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Answer №1

The name of the route in angular routing is actually case sensitive.

Therefore, we need to update PreviewStep to previewStep to align with the route name.

To address this issue, you can either modify the route name or implement a custom UrlSerializer.

import { DefaultUrlSerializer, UrlSerializer, UrlTree } from '@angular/router';

export class TitleCaseUrlSerializer extends DefaultUrlSerializer {
    public parse(url: string): UrlTree {
        function toTitleCase(url) {
            return url.split('/').map(segment => segment ? 
                segment[0].toUpperCase() + segment.substr(1) : 
                segment).join('/');
        }
        return super.parse(toTitleCase(url));
    }
}

@NgModule({
   imports: [ ... ],
   declarations: [ ... ],
   providers: [
        {
            provide: UrlSerializer,
            useClass: TitleCaseUrlSerializer
        }
   ]
})
