[SOLVED] [1.15.2] java.lang.NullPointerException: Sending packet

[Novârch]

I'm getting this error on a packet that sends on the player left clicking, the log doesn't show any of my code so I don't know what the problem is.

Here is the crash report: https://gist.github.com/Novarch129/6c6681dbd24eb9aa6856b75917b44c0f

And here is a git repo of my mod: https://github.com/Novarch129/JoJo-s-Blocky-Adventure

The attack message is at:  https://github.com/Novarch129/JoJo-s-Blocky-Adventure/blob/master/src/main/java/com/novarch/jojomod/network/message/SyncStandSummonButton.java

The input event is at: https://github.com/Novarch129/JoJo-s-Blocky-Adventure/blob/master/src/main/java/com/novarch/jojomod/network/message/SyncStandSummonButton.java

I would try setting breakpoints and making sure all of the data in your packet code is valid.

Also, you should post debug.log, it has much more information than a crashlog

Heres the log: https://gist.github.com/Novarch129/5f93bae9fc8c9b5dc7943cad95f1e0a1

I skipped all the lines that were just registries and chat.

I know that seems logical, but honestly modified logs are a bad idea, you don't know if you accidentally deleted something that was actually needed information.

 

*edit anyway, I don't see anything there, so I'm standing by my original thought that you should set some breakpoints and debug your packet code to make sure all the data is what you expect it to be and not null or something.

Howdy

Looks like this is null

TrackedEntity::

public void sendSpawnPackets(Consumer<IPacket<?>> p_219452_1_) {
      if (this.trackedEntity.removed) {
         LOGGER.warn("Fetching packet for removed entity " + this.trackedEntity);
      }

      IPacket<?> ipacket = this.trackedEntity.createSpawnPacket(); '<--- null here

Have you created a custom entity and not properly implemented createSpawnPacket?
