Laravel Nova Multiselect (on create Error Array to string)

Question

I try using multiselect when creating record but I get error Array to String. But when I update record everything is ok.

            Panel::make('Material', [
            MultiSelect::make('Select materials', 'material_id')
                ->options(Material::orderBy('name', 'ASC')->get()->pluck('name', 'id'))
                ->hideFromIndex(),
        ]),

I need hide this filed when creating record to use him on update.

Thanks.

What database type is material_id? Make sure it's a database field that allows to save array's.

One other thing that could cause this if you didn't cast the field in your model to array

<?php

namespace App\Models;

class Model
{
    protected $casts = [
        'material_id' => 'array',
    ];
}
