It seems like new \SplFixedArray($size) of type object<SplFixedArray> is incompatible with the declared type array<integer,object<Spa...\Collection\ValueType>> of property $data.
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..
