GenerateEntityFrameworkPrimaryKeyPropertyMaps throws null pointer exception (v6.0.0)

Most likely you don't have all the Keys mapped to the DTO from the Entity class and it can't find a matching property map for the key and this exception is what you get. It uses all keys so make sure you have those properties with matching name on the DTO, or have them mapped explicitly.

The exception doesn't tell you which one it is, you'll have to go look at all your mappings to see if Keys are matched.

If you don't have the keys in the DTO it doesn't know how to check if 2 items are equivalent to one another.
