How to Resolve ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: ‘someRoute’

The error message ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: ‘someRoute’ typically occurs in Angular applications when the Angular Router cannot find a corresponding route for a given URL. This can happen due to various reasons such as a missing route in your routing module, a typo in the URL, or incorrect navigation logic. Here’s a step-by-step guide on how to resolve this issue:

1. Check Your Route Configuration

Ensure that the route ‘someRoute’ is defined in your routing module. Routes are usually defined in a module-specific routing module or in the AppRoutingModule. Here is how a route might be defined:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { SomeComponent } from './some.component';

const routes: Routes = [
{ path: 'someRoute', component: SomeComponent }

imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
export class AppRoutingModule { }

Make sure that ‘someRoute’ is spelled correctly and corresponds to the path you are trying to navigate to.

2. Check Navigation Logic

If your route is correctly configured, review how navigation is triggered in your application. Navigation can be done programmatically using the Router service or through router links in your templates. Here’s how to navigate programmatically:

import { Router } from '@angular/router';

constructor(private router: Router) {}

navigate() {

For template navigation, make sure your router link is set up like this:

<a [routerLink]="['/someRoute']">Go to Some Route</a>

3. Review Route Parameters

If your route expects parameters and you are navigating without them, or with incorrect parameters, you will face this issue. For instance, if your route is configured as someRoute/:id and you navigate to just someRoute, it will not match any routes. Make sure to provide all required parameters:

this.router.navigate(['/someRoute', { id: 123 }]);

4. Wildcard Route to Handle Non-existent Routes

If users might enter a route that does not exist, consider adding a wildcard route to catch all unmatched routes and redirect them, or show a specific component:

const routes: Routes = [
{ path: 'someRoute', component: SomeComponent },
{ path: '**', redirectTo: '/someRoute' } // Redirects any other route to 'someRoute'

5. Check Module Imports

Ensure that your routing module (e.g., AppRoutingModule) is properly imported into your Angular application’s root module (usually AppModule). Without the proper import, your routes will not be recognized.

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

imports: [
// other imports
declarations: [AppComponent],
bootstrap: [AppComponent]
export class AppModule { }

6. Reload Your Application

Sometimes, changes might not be picked up until you restart your Angular development server. Stop the server, restart it, and see if the issue persists.

By following these steps, you should be able to diagnose and fix the routing error in your Angular application. If the problem continues, double-check all configurations and the console for other possible error messages that might give more clues.
