[v6] Possible bug on $user->syncRoles($array)

[helderneves91]

Hello, after upgrading to v6, I can't sync an array of role ids to an user.
As far I know, the v6 doesn't break the sync() method right? Am I missing something?

Controller

public function update(UserRequest $request, $id)
    {
        $validated_data = $request->validated();

        $user = User::findOrFail($id);
        $user->update([
            'company_id' => $validated_data['company_id'],
            'is_active' => $validated_data['is_active'],
            'name' => $validated_data['name'],
            'email' => $validated_data['email'],
            'department_id' => $validated_data['department_id'],
            'site_id' => $validated_data['site_id'],
        ]);

        //dd($validated_data['roles']);

        if (isset($validated_data['roles'])) {
            $user->syncRoles($validated_data['roles']);
        } else {
            $user->roles()->detach();
        }

        if ((int)$validated_data['is_active'] === 0)
        {
            $user->roles()->detach();
            $user->permissions()->detach(); // safe measure
        }

        return;
    }

Request

public function rules()
    {
        return [
            'company_id' => ['required', 'integer'],
            'is_active' => ['required', 'boolean'],
            'name' => ['required', 'string'],
            'email' => ['required', 'email:rfc,dns,filter'],
            'department_id' => ['required', 'integer'],
            'site_id' => ['required', 'integer'],
            'roles' => ['nullable'],
            'roles.*' => ['integer'],
        ];
    }

dd() the $validated_data($roles)

array:3 [▼ // app\Http\Controllers\UserController.php:147
  0 => "42"
  1 => "45"
  2 => "7"
]

The error (the role exists by the way)

Spatie \ Permission \ Exceptions \ RoleDoesNotExist
There is no role named `42` for guard `web`.

Closing: integers should be passed as integers not numeric strings, else they get treated as names: #2530
