I have problem with dropdown filter not working after hosting. This is my code

app/Livewire/Matakuliah.php (controller)

return view('livewire.matakuliah', [
            'title' => 'Mata Kuliah',
            'matakuliahs' => $matakuliahs,
            'jurusans' => Jurusan::all(),
            'prodis' => ProgramStudi::where('jurusan_id', $this->jurusan_id)->get(),
        ]);

resource/views/livewire/matakuliahModal.blade.php

<div class="form-group mb-3">
                        <label for="jurusan_id" class="fs_caption4">Jurusan</label>

                                @foreach ($jurusans as $jurusan)

This is the view of Program Studi Dropdown after hosting the laravel app
The Program Studi dropdown is empty

Program Studi dropdown should be show list filtered by Jurusan. In localhost, the Program Studi Dropdown is working

The Program Studi dropdown is shown

What should i do for fix that problem ?
Thank you so much for helping 🙂

I expect that Program Studi Dropdown filter by jurusan_id will be work normally in hosting server
