PluginMessaging: Expected a com.google.gson.JsonObject but was com.google.gson.JsonPrimitive (Velocity + Fabric)

Question

PluginMessaging: Expected a com.google.gson.JsonObject but was com.google.gson.JsonPrimitive (Velocity + Fabric)

Description

Whenever I change a users permissions using /lpv user permission set i get kicked by the fabric server because of Internal Exception: com.google.gson.JsonSyntaxException: Expected a com.google.gson.JsonObject but was com.google.gson.JsonPrimitive
It works the other way around though, so when i use /lp user permssion set the proxy syncs without any problems

Reproduction Steps

Install the latest version of Velocity
Install LuckPerms for Velocity
Install Fabric 1.18.1
Install LuckPerms for Fabric
configure Velocity to redirect to Fabric
Configure both instances as stated here and here to use MySQL and Plugin Messaging Channels to communicate with each other

Expected Behaviour

Fabric should sync permissions with Velocity without throwing an exception

Server Details

Velocity 3.1.2-SNAPSHOT-136
Minecraft 1.18.1 with Fabric Loader 0.13.3 and fabric-api-0.46.6+1.18

LuckPerms Version

v.5.4.18

Ok I think that should fix it. (you only need to update the Fabric server, not the proxy)

In my test, without fabricproxy also throw exception.
I think this issue is caused by proxy side, not related fabricproxy.

server.log (execute lpv networksync on proxy):

Please could you update to the latest version of LP on your proxy/server.

Not expecting it to fix the problem, but should at least give a more helpful error message. :)

It also seems like I have to be online on my server to trigger this error if that helps

After doing some tinkering of my own I came to the conclusion it's something caused by fabricproxy-lite.. which is awkward because it's absolutely crucial for getting a Fabric server running on a network

Server and proxy logs with FPL and running lpv networksync https://gist.github.com/emilyy-dev/19a6be901a07fc72c6703b8c5b6a69ce
Server only log without FPL and sending an update notification from the client https://gist.github.com/emilyy-dev/e1389be9cf61615299db9d99a21d43f6

@james58899 I'm not particularly familiar with FPL's codebase but most things I see are related with login stage, not play stage; is there anything that could potentially modify post-login packets? (specifically CustomPayloadC2S, as everything else seems to work fine)

@emilyy-dev Fabricproxy-lite only register packet receiver in login stage and should not touch any packet in play stage.

I will take a look why fabricproxy-lite caused this issue.

Well my testing assumes there are no issues at proxy level.. which may be a wrong assumption to make. Will conduct further testing.

Yeah, it works perfectly, thank you!
