Make sure you're doing the following

  • This isn't an issue caused by another plugin
  • You've checked for duplicate issues
  • You didn't use /reload

API method(s) used

  • WrappedDataWatcher.getEntityWatcher() / getWatchableObject()
  • WrappedDataWatcher.Registry.get()

Code

protected void getDefaultWatcher(Player player, Pose entityPose) {
        if (watcher == null) {
            watcher = WrappedDataWatcher.getEntityWatcher(player).deepClone();
            var wo3D = watcher.getWatchableObject(index3D);
            wo3D.setValue(value3D);
        }
        if (entityPose != null) {
            watcher.setObject(indexPose, WrappedDataWatcher.Registry.get(EnumWrappers.getEntityPoseClass()), mapPoseToNMS.get(entityPose));
        }
    }

Additional context
The problem occurs when a player connects "too fast", when the server has just "Done". If the player connects a few seconds later the problem does not occur. I'm not sure how I could get around this problem. Is this a bug in the initialization of Protocollibs or in my use?

Thank you for your help.
