Hi, 

Could you please open a support case for this issue and provide in the case the details of the scenario from which version did you upgrade? and attach to the case the QEM log with the error for further analysis. 

Thanks & regards, 

Orit

ya its a case of read the docs. Some are middleware generators where you call a function passing in a config... some are middleware ready to use and you just pass the function in.

A good way of telling is if you console log the function you'll see if it has the normal 3 param function... its middleware... if its anything else its a middleware generator/factory.
