Live search doesn't work but also no errors.

I can't find the error with this one. No error appears in my laravel.log so I tried tracing it but to no avail. I'm for any suggestions.

js

    $('body').on('keyup','#search-patients',function()
    {
        var keyword = $(this).val();

        $.ajax({
            type: "POST",
            url: "{{ route('searchPatients')}}",
            dataType: "json",
            data: {keyword: keyword,
                    _token: '{{csrf_token()}}'
            },
            success: function(res){
                    $('#dynamic-row').empty();
                    $('#dynamic-row').append(res);
                }
        });
    });

controller

    public function searchPatients(Request $request)
    {
            $keyword = $request->get('keyword');

            $patient_admissions = DB::table('patients')
            ->join('admissions', 'patients.id', '=', 'admissions.patient_id')
            ->select('patients.id','patients.last_name as lname', 'patients.first_name as fname', 'patients.middle_name as mname', 'patients.suffix_name as sname', 'patients.status as status', 'admissions.admission_date_time as admission', 'admissions.discharge_date_time as discharge')
            ->where(function ($query) use ($keyword) {
                                $query->where('patients.id', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.first_name', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.middle_name', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.last_name', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.suffix_name', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.address', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.birthdate', 'LIKE', '%'.$keyword.'%')
                                        ->orWhere('patients.status', 'LIKE', '%'.$keyword.'%');
                            })
                            ->get();
    
            return view('includes.partials.patientSearch', compact('patient_admissions'))->render();
    }
