Hello,

I have been working on a custom recipe class. As part of this recipe, I needed to read fluids from a JSON file, and had to write a custom handler to deal with this since there doesn't appear to be one (as with Ingredient for example). As far as I can tell, it works perfectly. It reads the recipe correctly from the JSON file. However, I'm not sure if I have done my PacketBuffer read and write methods correctly for my FluidIngredient class. The reason I say this is because when trying to run JEI, I get the following error in the log:

[20:48:05] [Render thread/FATAL]: Error executing task on Client
java.lang.NullPointerException: null

I know this has to be the issue, because when I disable the custom recipe from being serialized, JEI runs fine and the error disappears. I have attached the full log below, and have also given links to the relevant classes. In this case, they are FluidItem2FluidRecipeSerializer and FluidIngredient.

 

FluidItem2FluidRecipeSerializer: https://github.com/skiprocks999/ElectrodynamcisExperimental/blob/main/src/main/java/electrodynamics/common/recipe/categories/fluiditem2fluid/FluidItem2FluidRecipeSerializer.java

FluidIngredient: https://github.com/skiprocks999/ElectrodynamcisExperimental/blob/main/src/main/java/electrodynamics/common/recipe/recipeutils/FluidIngredient.java

 

This is new ground for me in terms of modding, so I imagine the mistake will be easy to spot.

Okay so I have made the changes you recommended plus a few more, but to no avail. I can't get anything from the log, and it looks like the write() method in the serializer nor the read() methods are even called. The links are the same as before, and I have attached the latest log as well.

I finally tracked down the error. It actually was coming from another class entirely. At least I know what the issue is being caused by now. As a quick question, can anyone point me to a list of fluid tags please. I can't seem to find one.
