Follow this template except for feature requests. Use pastebin when providing /protocol dump and any relevant errors.

Make sure you've done the following:

• You're using the latest build for your server version
• This isn't an issue caused by another plugin
• You've checked for duplicate issues
• You didn't use /reload

Description and relevant errors:

I added ProtocolLib to my plugins folder, with no other plugins installed. Then, I started the server and ran the command: /packet add play server map_chunk true. I then logged into the server. In the console, I received this error message: https://pastebin.com/KgdTbcqq

Looks like we don't currently support Long Array NBT tags. Should (hopefully, fingers crossed) be a simple fix
