@smuzaffar I didn't check to see if this actually complies. I'm going to let the PR testing do it.

An exception of category 'DictionaryNotFound' occurred while
   [0] Constructing the EventProcessor
   [1] Constructing module: class=MixingModule label='mix'
   [2] Calling ProductRegistry::initializeLookupTables
Exception Message:
No data dictionary found for the following classes:

  edm::Wrapper<std::vector<reco::GenMET> >
  std::vector<reco::GenMET>

Most likely each dictionary was never generated, but it may
be that it was generated in the wrong package. Please add
(or move) the specification '<class name="whatever"/>' to
the appropriate classes_def.xml file along with any other
information needed there. For example, if this class has any
transient members, you need to specify them in classes_def.xml.
Also include the class header in classes.h

A type listed above might or might not be the same as a
type stored in the Event (or Lumi or Run). Instead it might
be the type of a data member, base class, wrapped type, or
other object needed by a stored type. Below is some additional
information which lists the stored types associated with the
types whose dictionaries were not found:

  std::vector<reco::GenMET> (read from input)

Missing dictionaries are associated with these branch names:

  recoGenMETs_genMetCalo__SIM.
  recoGenMETs_genMetTrue__SIM.

If you do not need these branches and they are not produced
in the current process, an alternate solution to adding
dictionaries is to drop these branches on input using the
inputCommands parameter of the PoolSource.
