Description

When passing dictionary (map) variables through replicated (to server) functions, the value will not print out on the client. In 4.19.2 (CL-4033788) this caused a crash but in 4.20.2 (CL-4302132) and Main 4.21 (CL-4309299) it causes the PrintString to print nothing on the client.

Steps to Reproduce
  1. Open the UE4 Editor and create a new First Person template project
  2. Navigate to the FirstPersonCharacter Blueprint and open it
  3. In the Event Graph, create an event called "ServerMAP" and set Replicates to: "Run on Server" and check Reliable
  4. Add a Map (Dictionary) input to the "ServerMAP" event that takes an Integer and Bool
  5. From "ServerMAP" get the Keys, add them to a "ForEachLoop", and add the Array Element to a "PrintString"
  6. Add an input node such as "Y", call "ServerMAP" and connect it to the Pressed Exec
  7. From the Map input connect a "Make Map"
  8. Add a few key/value pairs to the "Make Map"
  9. Under Play change the Number of Players to "2"
  10. Then Play in a New Editor Window and press "Y" on the Client

Results: The PrintString prints nothing on the Client

Expected: The PrintString should properly loop through the keys and print them out on the Client
