Another 1.20.2 Issue

[wasn325]

• [x] This issue is not solved in a development build (Using 5.1.1-Snapshot)

Describe the bug I am not sure if this is a bug or I am just very stupid. I am creating a packetwrapper for SCOREBOARD_DISPLAY_OBJECTIVE and while trying to set the position (list, sidebar, belowName) I get the following error

com.comphenix.protocol.reflect.FieldAccessException: Field index 0 is out of bounds for length 0 at com.comphenix.protocol.reflect.FieldAccessException.fromFormat(FieldAccessException.java:49) ~[ProtocolLib.jar:?] at com.comphenix.protocol.reflect.StructureModifier.write(StructureModifier.java:316) ~[ProtocolLib.jar:?] at me.wasn325.coreapi.core.packets.WrapperPlayServerScoreboardDisplayObjective.setPosition(WrapperPlayServerScoreboardDisplayObjective.java:51) ~[coreapi.jar:?]

To Reproduce Steps to reproduce the behavior:

https://github.com/dmulloy2/PacketWrapper/blob/master/PacketWrapper/src/main/java/com/comphenix/packetwrapper/WrapperPlayServerScoreboardDisplayObjective.java#L55 This wrapper has almost the same structure as mine and should work for demonstrating (the problematic line is already marked)

Expected behavior A clear and concise description of what you expected to happen.

Screenshots I am not sure if this is possible, as the problem occurs before the scoreboard is finish and is visible to the Players

In 1.20.2 an enum (DisplaySlot) is used for the position instead of an integer, I added a wrapper for it in #2819
