Migrating C++ files from 5.6 to 5.7

I have recently tried to move my project across from UE 5.6 to 5.7.

Managed to flush out most of the errors.

Only issue I have now is MassRequirements and whatever is in MassEntityView

I have copied my MASS Processors over and wonder if there has been a change in the way I have to initialise or get references to Fragments now.

Anything that could be causing this?
