Call to undefined method Illuminate\Support\Facades\Validator::resolver()

What is it about ?

I am using Laravel 5.2 and update the composer by running the following command

composer require felixkiss/uniquewith-validator:2.*

I did this because I am trying to implement Multiple column Unique Validation. I mean Composite Key Validation.

I am following the instructions as mentioned here

What's the issue ?

When Laravel runs the below line.

$v = \Validator::make($request->all(), [
    'SubCategory' => 'required|max:25|min:5|unique_with:tblsubcategory,CategoryID',
    'CategoryID' => 'required',
]);

I get this error.

Call to undefined method Illuminate\Support\Facades\Validator::resolver()

Important

This was working fine in Laravel 5.1
