ZF2 How to show an error 404 for nonexistant actions

Question

I have a large site based on Zend Framework 2. URLs follow the standard pattern of domain.tld/module/action/otherstuff.

If someone types in a module that does not exist, they get a standard 404 page not found message. However, if the user goes to a valid module but enters an invalid action name, they get a message

Zend\View\HelperPluginManager::get was unable to fetch or create an instance for escape

How can I output a normal 404 error message instead of this message? I am guessing I am not catching something correctly somewhere, but I don't know where to start looking.

Here is the stack trace:
