Cant sycPermissions or givePermissionTo

[d-cerqueira]

I am trying to use the syncPermissions() method when I create and update users. However, I always get the same error, which is:

Call to a member function map() on null

At first I thought the view was not returning the correct format for the permissions, however, I found out the data was not the problem.

I decided to hardcode the functionality I wanted just to make sure I was not the problem, so I did this:

public function store(UserRequest $request): Redirect
{
    Gate::authorize('admin.users.create');

    User::query()
        ->create($request->validated());

    $user = User::query()->find(1);
    $user->givePermissionTo([dashboard.see']);


    return redirect()->route('admin.users.index');

}

But I still get the same error. I decided to take a look at the vendor folder and set some dd() to find what could be wrong and I found out that inside the HasPermission trait, on the givePermissionTo() method (line 401) it is trying to map over $this->permissions which is in fact null.

Can some help me out please?

I just found the problem. The error was actually between the keyboard and chair. I was casting the permissions to array and that was messing things up....
