It seems like
$this->createBoundingBox() of type array<string,double,{"no...uble","west":"double"}> is incompatible with the declared type array<integer,double>|false of property $bounds .
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..
