[1.8] [SOLVED] Invalid Packet string size error

[Himself12794]

I'm trying to send information to the server about location information from casting a spell client side. I'm getting the entity the player is looking at, casting the spell on that target, then telling the server to do the same. The only problem is that when the server (dedicated) receives the packet, I get a String exceeds maximum string size 22 > 20. However I am not sending any Strings. Here's my packet handler and message code on github:

 

https://github.com/Himself12794/powersAPI/blob/master/src/main/java/com/himself12794/powersapi/network/CastSpellInstantServer.java

 

and here's the SpellInstant class:

I only get this error on a dedicated server, otherwise it works as it should. Perhaps I'm sending the packet incorrectly?

Your channel is too long, it can only be 20 chars max. You set it here: https://goo.gl/f99Fc3

I just noticed that as well. Shrunk it and it worked. Thanks!
