Laravel – SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'namapenerima' cannot be null

I’m using a Livewire component, why is it still showing "cannot be null" even though all fields in the form have been filled out? I want the data that I fill in the form to be inserted into the database.

Bayar View

            <form wire:submit.prevent="store">
                @csrf
              
                <div class="form-group">
                  <label for="namapenerima">Nama Lengkap :</label>
                  <input type="text" name="namapenerima" class="form-control" value="{{ Auth::user()->name }}" placeholder="Masukkan nama lengkap Anda" required>
                </div>
              
                <div class="form-group">
                  <label for="email">Email:</label>
                  <input type="email" name="email" class="form-control" value="{{ Auth::user()->email }}" placeholder="Masukkan alamat email Anda" required>
                </div>
              
                <div class="form-group">
                  <label for="phone">Nomor Telepon:</label>
                  <input type="number" name="phone" class="form-control" value="{{ Auth::user()->phonenumber }}" placeholder="Masukkan nomor telepon Anda" required>
                </div>
              
                <div class="form-group" style="margin-top: 20px">
                  <label for="alamat">Alamat Lengkap:</label>
                  <textarea name="alamat" class="form-control" placeholder="Masukkan alamat lengkap Anda" required></textarea>
                </div>
              
                <button type="submit" class="submit-pesan" style="margin-top: 20px">Pesan Sekarang</button>
              </form>
