Compatibility introduced by
$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.

Duplication introduced by
This method seems to be duplicated in your project.

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.

You can also find more detailed suggestions in the “Code” section of your repository.
