Console error, server crashes

[Hazugg]

As you will see in the image, I had previously reported the same thing they said that in this update they would fix it but it continues to persist, my server is 1.16.5 and I just put the command to summon, the server it shows a big error, crashes

Sorry, I thought it's the same issue as the PetBlocks one, which is fixed in this new version. Could I please get a list of your plugins? You can type /plugins in your console and copy the output text.

[Hazugg]

My plugins

[Hazugg]

but I do not think it is plugin errors, I think it has to do with an incompatibility, since in itself it does not fall due to some complement itself, if not that the paper when executing the command falls altogether

[KP56]

It's caused by incompatibility of fake players with some plugin - I'll need to figure out, which one is it.

[Hazugg]

You could try with CMI that is base of the server is like an essentials 2

[KP56]

Ok thank you for your help.

[KP56]

By any chance, do you have an outdated protocollib?

[Hazugg]

I'm using the latest version, but I'm going to try the development version for paper to see if it could be the problem

[Hazugg]

I just installed the development version and the problem still persists

Ok, can I see the entire error? It should tell me, which plugin causes this issue.

[KP56]

I think I know. I did some tests and it's a combination of Citizens and ProtocolLib, which causes these issues.

Try this version of Fake Players - maybe it will work.

[KP56]

Does it mean it works?

[Hazugg]

I am testing with it is, first time I did summon I invoked a bot, but I wanted to do it again and I got the same error again, and what is valid is in itself that it is not an error of some plugin itself , of course what should cause some plugin I think, but if what happens is that the whole paper crashes

when doing summon again as mentioned it gave the same error again

I send you the complete error file:

CONSOLE ERROR.zip

It is worth mentioning that it is not something from Citizens since I am testing on another server without that plugin and it continues to persist, of course I still have a protocol

[Hazugg]

these are the plugins on the server that I am retesting

[Hazugg]

Does it mean it works?

I closed it by mistake

Maybe this one?

[KP56]

I think you may be using an old/custom paper version. I'm so sorry for wasting so much of your time. Why haven't I realized it earlier? I decompiled the newest paper and I cannot find a b() function, which calls a writeAndFlush() function in a NetworkManager class (this is where the error is according to the stacktrace you provided). If it isn't a fork you paid for, you should definetely switch to purpur (https://github.com/pl3xgaming/Purpur).

[Hazugg]

I tried what he sent me and the third summon failed again: /

I downloaded the paper from the same official page: https://papermc.io/ But if it is a matter of the paper then I will try updating it to the latest version or use the one you sent me, thank you!

[KP56]

I hope it is.
