Isi form otomatis

Saya sedang berlajar codeigniter 4 membuat form dan form tersebut ketika di klik kode pada list (select/option) maka keluar namanya setelah diconsole errornya seperti berikut:

GET http://localhost:8080/api/home/110 404 (Not Found) VM148:1 Uncaught (in promise) SyntaxError: Unexpected end of JSON input

untuk source tampilan

<div class="form-group col-3"> <label for="akun1">Nama Akuntansi</label> <select class="form-control" name="akun1" id="akun1"> <option value="" selected disabled>-- Silahkan pilih --</option> <?php foreach ($kode as $kade) : ?> <option value="<?= $kade['kode']; ?>" id="akun1"><?= $kade['kode']; ?></option> <?php endforeach ?> </select> <div id=" validationServer03Feedback" class="invalid-feedback"> <?= validation_show_error('akun1'); ?> </div> </div>

                        <div class="form-group col-3">
                            <label for="deb1">Debet</label>
                            <input type="text" class="form-control <?= (validation_show_error('deb1')) ? 'is-invalid' : ''; ?>" id="deb1" name="deb1" placeholder="Isi jumlah debet" value="">
                            <div id="validationServer03Feedback" class="invalid-feedback">
                                <?= validation_show_error('deb1'); ?>
                            </div>
                        </div>

controller API nya: <?php namespace App\Controllers\Api; use App\Models\KodeModel; use CodeIgniter\API\ResponseTrait; use CodeIgniter\RESTful\ResourceController; class Home extends ResourceController { use ResponseTrait; public function show($kd = null) { $model = new KodeModel(); $data = $model->find($kd);

    return $this->respond($data);
}

}

dan javascritnya <script> $('#akun1').on('change', (event) => { getCau(event.target.value).then(kode => { $('#deb1').val(kode.nama); }); });

    async function getCau(kd) {
        let response = await fetch('/api/home/' + kd)
        let data = await response.json();
        return data;
    }
</script>
