The trait Illuminate\Queue\Seriali...estoresModelIdentifiers requires some properties which are not provided by Algolia\ScoutExtended\Se...le\AggregatorCollection: $id, $class, $connection, $relations
It seems like $this->getSerializedProp...n(...) { /* ... */ }))) of type Illuminate\Contracts\Database\ModelIdentifier is incompatible with the declared type array of property $items.
Our type inference engine has found an assignment to a property that is incompatible
with the declared type of that property.
Either this assignment is in error or the assigned type should be added
to the documentation/type hint for that property..
This check looks for calls to methods that do not seem to exist on a given type.
It looks for the method on the type itself as well as in inherited classes or
implemented interfaces.
This is most likely a typographical error or the method has been renamed.
