Question How fixing Invalid player data?

[ProKoksPL1]

Witam, mam problem z połączeniem graczy z serwerem, wyświetla mi się komunikat "Nieprawidłowe dane gracza". Nadmienię, że nowy problem dotyczy silnika Paper, a inne silniki nie mają tego błędu, a ja chcę skorzystać z silnika Paper. Czy masz jakieś rozwiązanie tego problemu? Co moglibyśmy zrobić, aby temu zaradzić?

I am encountering this "invalid player data" as well on Minecraft Java client 1.20.2 when connecting to the latest Paper 1.20.2 Build 249.

I created a new VM (2core 8gb RAM), installed and ran Vanilla Minecraft 1.20.2, and tested I could connect via my Minecraft client successfully. Then...

1) I stopped the Minecraft "server.java" process.
2) Replaced the (vanilla) server.jar with "paper-1.20.2-249.jar"
3) Started Paper - logs show it migrated world data, etc.

However, when I try to connect my Minecraft client, I receive "Invalid Player Data" and the paper server log shows:

Any thoughts?

I also am having this issue, with Paper 1.20.2 r259. I'm trying to convert a 1.20.2 vanilla world:

I fixed this by downgrading the server to version paper-1.20.2-214.jar, logging in as the player (which then worked) then upgrading the server again. I suspect this is because of:

#215	431e641Fixup player profile getters and constructor to expected nullability (#9770)

 

[electronicboy]

It's due to the upstream merge, the latest build should fix it

 

[Zelphium]

Correction: build 246 is the highest that currently works for converting characters. 247 does not work:

Correction: build 246 is the highest that currently works for converting characters. 247 does not work: #247 acc6d01Updated Upstream (Bukkit/CraftBukkit/Spigot) (#9861) Thank you, Electronicboy. Really appreciate it! I can confirm the new build 260 doesn't have this error!

 

[Dustin]

Thank you Electronicboy!... I can also confirm the issue is resolved with build 260!
