Troubleshoot: Angular 12 HTTP request not passing correct parameters

When working with my service.ts file, I encountered an issue while calling a method that triggers an http request to the specified API endpoint:
users/1111/state/2222
The numbers 1111 and 2222 represent the userId and stateId respectively.

This is the snippet of code from my service.ts file:

public getParams(userId: number, stateId: number): Observable<MyModel> {
   return this.get(`users%2F${userId}final-rosters%2F${stateId}`)
     .pipe(map(response => response.body));
 }

Now, in my component.ts file. I am invoking the above method in this manner:

public getUser(
    userId: number,
    stateId: number,
  ): void {
    this.myService.getParams(userId, stateId)
      .subscribe(result => {
        this.myModel.next(result);
        console.log('GET DATA ', result);
      });
  }

After inspecting the tools, I noticed the following URL path being generated:

I am currently facing challenges in converting the given URL path into one that correctly incorporates the two required parameters.

Make sure to define your service URL correctly:

public fetchUserData(userId: number, stateId: number): Observable<UserDetails> {

   const apiUrl = 'users/${userId}/final-rosters/${stateId}';
   return this.fetch<UserDetails>(apiUrl), { observe: 'response' });

 }
