Players cant chat anymore

[cynicalmax]

Server console when someone writes a message:

[23:34:06 WARN]: [VentureChat] Plugin VentureChat v3.6.0 generated an exception while executing task 17293 java.lang.NullPointerException: Cannot invoke "mineverse.Aust1n46.chat.json.JsonFormat.getJsonAttributes()" because "format" is null at mineverse.Aust1n46.chat.utilities.Format.convertPlaceholders(Format.java:117) ~[VentureChat-3.6.0.jar:?] at mineverse.Aust1n46.chat.utilities.Format.convertToJson(Format.java:73) ~[VentureChat-3.6.0.jar:?] at mineverse.Aust1n46.chat.listeners.ChatListener.handleTrueAsyncPlayerChatEvent(ChatListener.java:487) ~[VentureChat-3.6.0.jar:?] at mineverse.Aust1n46.chat.listeners.ChatListener$1.run(ChatListener.java:53) ~[VentureChat-3.6.0.jar:?] at org.bukkit.craftbukkit.v1_20_R1.scheduler.CraftTask.run(CraftTask.java:101) ~[paper-1.20.1.jar:git-Paper-117] at org.bukkit.craftbukkit.v1_20_R1.scheduler.CraftAsyncTask.run(CraftAsyncTask.java:57) ~[paper-1.20.1.jar:git-Paper-117] at com.destroystokyo.paper.ServerSchedulerReportingWrapper.run(ServerSchedulerReportingWrapper.java:22) ~[paper-1.20.1.jar:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) ~[?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) ~[?:?] at java.lang.Thread.run(Unknown Source) ~[?:?]

Did you edit the json formatting section in the config? It looks like whatever player is trying to chat has no json format, which is usually a configuration issue. You can try using a fresh config to debug.

I have already delete my config and re-generate a new one

[SoraSushi776]

I know where my reason lies: my Java version is incorrect, I am using Java 14, but the 1.16 server only supports Java 14 and cannot use Java 17.

When I use Java 17, it will report the following error ‘’‘ Unsupported Java detected (61.0). Only up to Java 14 is supported. ’‘’

I solved this problem by using an older version of VentureChat Hope this can help you
