Describe the bug
When I try to create packet using ProtocolManager#createPacket, it produces error.

Caused by: java.util.NoSuchElementException: No value present
        at java.util.Optional.get(Optional.java:143) ~[?:?]
        at com.comphenix.protocol.wrappers.WrappedChatComponent.<clinit>(WrappedChatComponent.java:49) ~[ProtocolLib.jar:?]
        ... 33 more

Here's line that produced error:

PacketContainer openSign = ProtocolLibrary.getProtocolManager().createPacket(PacketType.Play.Server.OPEN_SIGN_EDITOR);

Hi,

thank you for sharing the information. The cause of the problem is probably that you are running a MC server with Mojang Mappings and not spigot mappings.
ProtocolLib currently only uses the Spigot Mapping of the required class name in https://github.com/dmulloy2/ProtocolLib/blob/master/src/main/java/com/comphenix/protocol/wrappers/WrappedChatComponent.java#L28.

I will see if I can reproduce this and fix the problem in the next couple of days
