Can not use '$query' in slim 3 with Laravel eloquent

Question

I use slim 3 for microservice for that i install laravel eloquent and i write a laravel query like following

use Illuminate\Database\Capsule\Manager as DB;

DB::enableQueryLog();

$faqs = DB::table('rental_faq')
    ->where('id', '!=', '')
    ->where(function ($query) {
        $query->where('isActive', '=', 1)
            ->orWhere('isDelete', '=', 'no');
    })
    ->get();

then the problem is it shows a error like following

" There was an error parsing JSON data Unexpected token I in JSON at position 743 "

I want to perform and_where and or_where operation separated parenthesis

         ->where('isActive',1)
         ->where('isDelete','no')
         ->where(function ($query) use($maincat,$subcat) {
                $query->where('main_category',$maincat)
                      ->whereRaw('FIND_IN_SET(?,sub_category)',[$subcat]);

 ->get();
