Paper: Internal server error in upgrading from Paper-31(1.15.1) to paper-33(1.15.1)

[BillZhucn]

What behaviour is expected:

___What you expected to see___
Enter The End

What behaviour is observed:

___What you actually saw___
If anyone trying to pass the activated end portal they will be kicked for 'Internal server error'.

Steps/models to reproduce:

___This may include a build schematic, a video, or detailed instructions to help reconstruct the issue___
When I change the server from Paper-31.jar(1.15.1) to the up-to-date Paper-33.jar without changing the map (The map is created under Paper-31(1.15.1) environment) , if anyone trying to pass the activated end portal they will be kicked for 'Internal server error' and the only way to let them in is to delete the file in the playerdata folder. And if they try to teleport to the end, the error will come back again.

Plugin list:

___A list of your plugins___
AuthMe, ColorMOTD-Reremake, Essentials, EssentialsAntiBuild, EssentialsChat, EssentialsGeoIP, EssentialsProtect, EssentialsSpawn, GroupManager, IllegalStack, NotBoom, PlayerReport, PluginManager, ProtocolLib, SkinsRestorer, TitleManager, Trash, Vault, WorldEdit

Paper build number:

___This can be found by running /version on your server. latest is not a proper version number; we require the output of /version so we can properly track down the issue.___
Paper-31→Paper-33 (1.15.1)

Anything else:

___Anything else you think may help us resolve the problem___

Did you not check your console or logs?

Internal server error is just a front facing "nice" message to let you know something went wrong. The details are _always_ in the console and logs.

This morning with Paper-33

I cannot understand this, plz help me

[BillyGalbreath]

Did you even read it? It says what the issue is in plain English. Hint: It's not a Paper issue.

@BillyGalbreath With respect, Unhandled exception occured in onPacketSending(PacketEvent) for ColorMOTD-Reremake java.lang.IllegalArgumentException: Cannot translate null text isn't going to be "plain english" to everyone.

Yes it appears to be a plugin issue, not paper, and I imagine you get issues like this a lot, but that's no reason to be hostile to them. A simple "Sorry this isn't something we can help with, contact the author of X" would have worked just fine, please consider that in future.

@BillZhucn At a quick glance, might be worth checking your config file for ColorMOTD-Reremake exists, and that it has a message set for the maintenance mode motd. If you're still having trouble though, the place to ask would be here https://github.com/Ghost-chu/ColorMOTD-Reremake.
