404 when using a variable in URL- error: No query results for model [App\Models\Seeker]

Im calling from the angular front side to my laravel back end. When I use a variable in the url (USERID) it gives me a 404 error.

When I remove the USERID from the url it works and reach the function in the server.

Client side:

  getSeeker(userID: number) {
    return this.http.get(`${this.endPoint}/${userID}/getSeekerProfile`, 
      {headers: this.getTokenHeaders()})
  }

Server side:

    Route::get('candidate/{userID}/getSeekerProfile',   'CandidateController@getSeekerProfile');

Error on client side:

GET http://localhost:8000/api/headhunter/candidate/363/getSeekerProfile 404 (Not Found)

Error on server side:

message: "No query results for model [App\Models\Seeker]."

the targted function (getSeekerProfile): PS - i also tried to just return dd('reached') and removing the (User $userID) parameter.

    public function getSeekerProfile(User $userID)
    {
        dd($userID);
    }

I cant really find the problem. Im not even using the Seeker model in relation to this piece of code.

Any ideas will be most welcome.

Thanks.
