Controller

public function updateLabor(Request $request)
    {
        $claims =  Claim::where('id', $request->id)->first();
        $claim_decode =  json_decode($claims->dynamodb_tabels_data,1);
        
        $data_claim = [];
        foreach($claim_decode['truck_estimating_result'] as $k=>$item){
            array_push($data_claim,$item);
            $data_claim[0][$k]->part_type->S = $request->part_type;
            $data_claim[0][$k]->labor_hr->N = $request->labor_hr;
            $data_claim[0][$k]->labor_type->S = $request->labor_type;
            $data_claim[0][$k]->paint_labor->N = $request->paint_labor;
            $data_claim[0][$k]->price->N = $request->price;
            $data_claim[0][$k]->part_taxed->N = $request->part_taxed;

        }
        dd($data_claim[0][1]);

        $result = $claims->update(['dynamodb_tabels_data'=>json_encode($claim_decode)]);
        
        if($result) {
            return response()->json([
                'data_claim' => $data_claim,
            ]);

            $.ajax({
            async: false, 
            type: "POST",
            url: "{{route('claim.updateLabor')}}",
            
            headers: { 
                'X-CSRF-Token' : $("[name='_token']").val()
            },
            data: {
                'data': data, 
                'id': id,
            },
            success: function(response) {
                // Toast message
                }
                })
            });
