It seems like $mediaembed_cache of type object<phpbb\mediaembed\cache\cache> is incompatible with the declared type object<phpbb\mediaembed\cron\purge> of property $mediaembed_cache.
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
@param
annotations where the type inferred by our type inference engine differs from the declared type.It makes a suggestion as to what type it considers more descriptive.
Most often this is a case of a parameter that can be null in addition to its declared types.
