		0 ignored issues – show Compatibility introduced 2016-12-06 13:33 UTC by Report Bug Copy Issue Report `$unit` of type `object<PhpJsonRpc\Core\Invoke\AbstractInvoke>` is not a sub-type of `object<PhpJsonRpc\Core\Invoke\Error>`. It seems like you assume a child class of the class `PhpJsonRpc\Core\Invoke\AbstractInvoke` to be always present. This check looks for parameters that are defined as one type in their type hint or doc comment but seem to be used as a narrower type, i.e an implementation of an interface or a subclass. Consider changing the type of the parameter or doing an instanceof check before assuming your parameter is of the expected type. Loading history...

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.
