Same PHP Code not working anymore

I have written a code to select a specific portion of the data from a table and display it in a new page. It was working fine before. All we did was introduced a new field and then reverted back. I am worried about the impact on the application due to these minor changes. I am using the following code:

public function chargeAwait(Request $request) { $createdDate = Carbon::now()->subDays(7)->toDateString(); $results = Chargeback::where('dispute_status', 'Disputed - Awaiting for Response') // ->whereDate('dispute_date','<=', $createdDate) ->where(function ($query) use ($createdDate) { $query->where(function ($subQuery) use ($createdDate) { $subQuery->where('action', 0) ->whereDate('dispute_date', '<=', $createdDate); }) ->orWhere(function ($subQuery) use ($createdDate) { $subQuery->where('action', 2) ->whereDate('dispute_date', '<=', $createdDate); }); }) // ->where('action',0)->orWhere('action',2) ->orderBy('dispute_date', 'desc')->paginate(pagination_limit()); return view('escalation.chargeawait', compact('results')); }

This code considers cases where dispute status is Disputed - Awaiting for Response and populates it in a new page of the application. It used to do that before. But the page is totally blank.

Any help would be appreciated.
