So i'm having an issue, i've been updating my mod to 1.13 from 1.12, and the custom crafting table that i've created now crashes the game whenever it's opened.

I've updated the code to match the code from the vanilla GuiCrafting class.

 

Here's the crash log:

Apparently something in GuiButtonRecipe.render is null, but i can't figure out what it is, i've initialized everything in my GuiCarpentersTable class (I think).

Here's the for GuiCarpentersTable

And here's the code for the BlockCarpentersTable

 

I have no idea what's wrong, and i've tried to step through the debugger in Intellij, but i don't find anything wrong.

You need to register your Gui:

 

ModLoadingContext.get().registerExtensionPoint(ExtensionPoint.GUIFACTORY,
                () -> (OpenContainer oc) -> { 
});

Yeah i've already done that, here's the code

The registerExtensionPoint points to the handleGuiRequests method
