When I create a NetworkVariable<FixedString512Bytes> in Unity.Netcode an error occurs on a client:

KeyNotFoundException: The given key was not present in the dictionary.
System.Collections.Generic.Dictionary`2[TKey,TValue].get_Item (TKey key) (at <695d1cc93cca45069c528c15c9fdd749>:0)
Unity.Netcode.NetworkManager.TransportIdToClientId (System.UInt64 transportId) (at Library/PackageCache/com.unity.netcode.gameobjects@1.0.0-pre.4/Runtime/Core/NetworkManager.cs:1285)
...

This only happened if three clients connected. And it didn’t happen when two clients connected.
When I use FixedString64Bytes everything is ok.

How can I use a 512 byte string as NetworkVariable?

It is because of limitation of UNet transport
