Fetch table row by id Laravel

I have a small project on Laravel and I wanted to fetch table rows by id and display in a Popup modal. I tried 'where' condition but it is not responding anything. How to do that? This is my Database Table (biniyojan_details) [1]: https://i.stack.imgur.com/GVd79.png Here is my code..

///Controller///

public function biniyojan_popup_details(Request $request)
{

    $biniyojan_popup_details = DB::table('biniyojan_details')
    ->leftJoin('biniyojan','biniyojan.biniyojan_id','biniyojan_details.biniyojan_id')
    ->select('biniyojan_details.*','biniyojan.biniyojan_id','biniyojan.date','biniyojan.ab','biniyojan.behora')
    ->where('biniyojan_details.details_id', '=', 'biniyojan_details.biniyojan_id')
    ->get();
    return response()->json(['biniyojan_popup_details' => $biniyojan_popup_details]);
}

///Popup modal script///

<script>
    $(document).ready(function() {
        $('.view_btn').click(function(e) {
            e.preventDefault();
          
            var id = $(this).closest('tr').find('.id').text();

            $.ajax({
                type: "GET",
                url: " {{ route('biniyojan_popup_details') }}",
                data: {

                    'checking_viewbtn': true,
                    'id': id,
                },
                //success: function(response){


                success: function(data) {
                    var html = '';
                    var biniyojan_popup_details = data.biniyojan_popup_details;
                    if (biniyojan_popup_details.length > 0) {
                        for (let i = 0; i < biniyojan_popup_details.length; i++) {
                            html += `
