Cant create model with implements hasMedia and InteractsWithMedia

[AUAboi]

When I try to create a model with hasMedia and InteractsWithMedia, i get error:

Method 'Spatie\MediaLibrary\MediaCollections\Models\Collections\MediaCollection::jsonSerialize()' is not compatible with method 'Illuminate\Database\Eloquent\Collection::jsonSerialize()'

Not exactly sure what could be causing this

Figured out the issue, solved by installing latest release. Documentation has the buggy version in installer.
