Laravel 5.4 detecting variable in developing mode but not in production mode

I am learning laravel and for my practicing purpose I am working on a project. When that app run in local machine it work perfectly but in live server it doesn't. Whats wrong here? I know it's kind of weird but just cant figure it out.

Here is my view

@foreach($product_details as $product_detail)
    <div data-repeater-item class="mt-repeater-item">
        <div class="mt-repeater-row">
            <div class="col-md-2"></div>
            <div class="col-md-3">
                <label class="control-label">Title</label>
                <input type="hidden" name="indicator_id" value="">
                <input name="title" type="text" placeholder="Title" class="form-control" value="" /> </div>
            <div class="col-md-6">
                <label class="control-label">Description</label>
                <textarea name="description" type="text" placeholder="Description" class="form-control description content" ></textarea> </div>
            <div class="col-md-1">
                <a href="javascript:;" data-repeater-delete class="btn btn-danger mt-repeater-delete">
                    <i class="fa fa-close"></i>
                </a>
            </div>
        </div>
    </div>
@endforeach

Here is Controller

$product_details = IndicatorDetails::where('indicator_id',$id)->get();

return view('admin.indicator.indicator_edit')->with('product_details',$product_details);

And Model

class IndicatorDetails extends Model
{
    protected $fillable = ['title','description','indicator_id'];
    public function indicator()
    {
        return $this->belongsTo(Indicators::class);
    }
}

Thanks in advance.
