Validation multiple insert data laravel ajax

Question

i need some help. I want to store multiple data and validation using laravel ajax, and i want to display error validation like that :

In inspect elemen, error validation is displayed, but when i want displayed in bottom form input, error validation not displayed.

This my validation in controller

$val    =    Validator::make($request->all(), [
                 'nim.*'     =>  'required',
                 'abs.*'     =>  'required|numeric|between:1,100.00',
                 'tgs.*'     =>  'required|numeric|between:1,100.00',
                 'utsm.*'    =>  'required|numeric|between:1,100.00',
                 'uasm.*'    =>  'required|numeric|between:1,100.00',
             ],
             [
                 'nim.*.required'    =>  'NIM harus diisi',
                 'abs.*.required'    =>  'Kehadiran harus diisi',
                 'abs.*.numeric'     =>  'Kehadiran harus angka',
                 'abs.*.between'     =>  'Kehadiran antara angka 1.00 - 100.00',
                 'tgs.*.required'    =>  'Tugas harus diisi',
                 'tgs.*.numeric'     =>  'Tugas harus angka',
                 'tgs.*.between'     =>  'Tugas antara angka 1.00 - 100.00',
                 'utsm.*.required'   =>  'UTS harus diisi',
                 'utsm.*.numeric'    =>  'UTS harus angka',
                 'utsm.*.between'    =>  'UTS antara angka 1.00 - 100.00',
                 'uasm.*.required'   =>  'UAS harus diisi',
                 'uasm.*.numeric'    =>  'UAS harus angka',
                 'uasm.*.between'    =>  'UAS antara angka 1.00 - 100.00',
             ]);

            if($val->fails()) {
                return response()->json(['error' => $val->errors()]);
            }

This my view for form input data and ajax

<form id="storeNilai" method="post">
@csrf

<tbody>
  @php $no = 1; @endphp
  @foreache ($mahasiswa as $mhs)
    <tr>
      <td class="text-center">{{ $no++ }}</td>
      <td>
        <input type="hidden" name="nim[]" id="nim[]" value="{{ $mhs->nim }}" readonly>
        {{ $mhs->nim }}
      </td>
      <td>{{ $mhs->name }}</td>
      <td>
        <input type="text" class="form-control" size="1" name="abs[]" id="abs[]">

      </td>

      </td>
    </tr>
  @endforeach

<button type="submit" class="btn btn-primary ml-1">Simpan</button>

<script>
$(document).ready(function () {

    e.preventDefault();

    $('#abs_error').html();
    $('#tgs_error').html();
    $('#utsm_error').html();
    $('#uasm_error').html();

    $.ajax({
      url: "{{ route('input-nilai.post') }}",
      method: 'POST',
      data: new FormData(this),
      contentType: false,
      cache: false,
      processData: false,
      dataType:"json",

      success: function(data) {
        if(data.errors) {
          if(data.error.abs) {
            $("#abs_error").html(data.error.abs[0]);
            $("#abs").addClass("is-invalid");
          }

          if(data.error.tgs) {
            $("#tgs_error").html(data.error.tgs[0]);
            $("#tgs").addClass("is-invalid");
          }

          if(data.error.utsm) {
            $("#utsm_error").html(data.error.utsm[0]);
            $("#utsm").addClass("is-invalid");
          }

          if(data.error.uasm) {
            $("#uasm_error").html(data.error.uasm[0]);
            $("#uasm").addClass("is-invalid");
          }
        }
      },
    });
  });
});
