Failed to find DataWatcher Object for EntityHorse

[SirZontax]

I used your API to give all players in the targets world the glow effect (only for him) and then this error message came up:

I'm using the 1.4.13-SNAPSHOT of the GlowAPI with the 3.7.8-SNAPSHOT version of PacketListenerAPI on Spigot 1.16.2
