Laravel fill with enum attribute gives error

Question

I have an Enum like:

<?php

namespace App\Models\helpers\Enums;

enum ComissionamentoVendedor: string
{
    case Faturamento = 'No faturamento';
    case Pagamento = 'Após o pagamento pelo cliente';
}

And I have a model that uses this Enum

...
    public $casts = [
        'comissionamento_momento' => ComissionamentoVendedor::class,
    ];
...

But when I try to save it I get an error:

$vendedor = new Vendedor;
$vendedor->fill($atributos);
$vendedor->save();

The error is ErrorException: Attempt to read property "value" on string

It happens on the file vendor/illuminate/database/Eloquent/Concerns/HasAttributes.php:951

 protected function setEnumCastableAttribute($key, $value)
 {
     // $value here is a string, a valid value from ComissionamentoVendedor Enum, sent by the frontend but looks like Laravel expects to be an Enum
     $this->attributes[$key] = isset($value) ? $value->value : null;
 }

Am I doing something wrong? I'm actually using Lumen 8.3.3.

Unless you can upgrade the Illuminate libraries being used in your application you don't have the feature of the ability to have the cast get an Enum from a string for you; you will have to pass an Enum. You can get the Enum you need from a string using the from method:

$enum = ComissionamentoVendedor::from($value);

If you are not sure if this value is actually a valid value for the Enum you can use the tryFrom method:

$enum = CommissionamentoVendedor::tryFrom($value) ?? $defaultEnum;
