How to make DataCollection from MyInterface

[dfiliuk]

I try to get a collection of MyInterface Items.

But I got an error: "Exception: Unable to normalize items".

On laravel-data/src/Resolvers/DataCollectableFromSomethingResolver.php:158

I had my interface:

Interface MyInterface extends BaseData
{
    public function getMetadataType(): MetadataType;
}

class MyData extends Data implements MyInterface
{
    public bool|null $p_1;
    public bool|null $p_2;
    public bool|null $p_3;

    public function getMetadataType(): MetadataType
    {
        return MetadataType::METADATA;
    }
}

And usage:

#[DataCollectionOf(MyInterface::class)]
public DataCollection|null $metadata;

You're going to need to write your own normalizer: https://spatie.be/docs/laravel-data/v4/advanced-usage/normalizers
