Laravel route Error: Route [login] is not definded - laravel

Question

I'm developing an Laravel API, and finding a bit difficult to find the right answer for following problem. The problem is I'm having that when I query my group/join endpoint I'm getting the following error.
InvalidArgumentException: Route [login] not defined. in file\vendor\laravel\framework\src\Illuminate\Routing\UrlGenerator.php on line 372
When I query my GroupController#getAll I'm getting results from the database. So now I'm a bit flustered about what to try next.
My Group Controller code (only the requests that are implemented)
/**
* #param CreateGroupRequest $request
*/
public function createGroup(CreateGroupRequest $request){
$data = $request->get('group', []);
}
/*
* #param JoinGroupUserRequest $request
*/
public function joinGroup(JoinGroupUserRequest $request){
$group_id = $request->group_id;
$user_id = $request->user_id;
$data = $this->groupService->joinGroup($group_id, $user_id);
return response()->json([], 201);
}
My Group repository
class GroupRepository{
/*
Get a new instance of empty Group Model
*/
public function GetModel(){
return new Group();
}
/**
* #param int $private
* #return mixed
*/
public function GetAllGroups($private = 0){
$groups = Group::where('group_private', $private)->get();
return $groups;
}
/**
* #param array $data
* #return Group
*/
public function CreateGroup(array $data){
$group = $this->GetModel();
$group->fill($data);
$group->save();
return $group;
}
public function AddUserToGroup(int $group_id, int $user_id){
$group_user = new GroupUsers();
$group_user->group_id = $group_id;
$group_user->user_id = $user_id;
$group_user->save();
return $group_user;
}
}
My GroupService
class GroupService
{
private $groupRepository;
/**
* GroupService constructor.
* #param php $groupRepository
*/
public function __construct(GroupRepository $groupRepository){
$this->groupRepository = $groupRepository;
}
/*
* Gets all Groups
*/
public function getAll()
{
return $this->groupRepository->GetAllGroups();
}
public function joinGroup($group_id, $user_id){
return $this->groupRepository->AddUserToGroup($group_id, $user_id);
}
}
My api routes
Route::group(['middleware' => 'web', 'prefix' => 'auth'], function () {
Route::post('login', 'AuthController#login');
Route::post('signup', 'AuthController#signup');
Route::get('social/{provider}', 'AuthController#signupSocial');
Route::get('callback/{service}', 'AuthController#callback');
Route::group(['middleware' => 'auth:api'], function() {
Route::get('logout', 'AuthController#logout');
Route::get('user', 'AuthController#user');
});
});
Route::group(['middleware' => 'auth:api', 'prefix' => 'group'], function () {
Route::get('/', 'GroupController#getAll');
Route::post('join', 'GroupController#joinGroup');
});

"user_id": "1"
}
Now what I have tried is
Cleared my route cache
Named my login route which gave a MethodNotAllowedException
Can someone push me in the right direction ?

Answer 1

The solution was to add the Accept header with application/json
