As a way to practice modding I'm trying to add signs to my 1.19.2 mod, but when placing the sign and opening the sign edit screen it crashes with this log: https://mclo.gs/hxLFTGn

 

I can't find any info on the crash so i don't know what to do anymore.

package com.an12854.leanmod.block.entity;

import com.an12854.leanmod.Leanmod;
import com.an12854.leanmod.block.ModBlocks;
import net.minecraft.world.level.block.entity.BlockEntityType;
import net.minecraftforge.eventbus.api.IEventBus;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;
import net.minecraftforge.registries.RegistryObject;

public class ModBlockEntities {
    public static final DeferredRegister<BlockEntityType<?>> BLOCK_ENTITIES =
            DeferredRegister.create(ForgeRegistries.BLOCK_ENTITY_TYPES, Leanmod.MODID);

    public static final RegistryObject<BlockEntityType<ModSignBlockEntity>> SIGN_BLOCK_ENTITIES =
            BLOCK_ENTITIES.register("sign_block_entity", () ->
                    BlockEntityType.Builder.of(ModSignBlockEntity::new,
                            ModBlocks.LEAN_WALL_SIGN.get(),
                            ModBlocks.LEAN_SIGN.get()).build(null));
    public static void register(IEventBus eventBus) {
        BLOCK_ENTITIES.register(eventBus);
    }
}

Here is the custom BlockEntities

Can you post your Screen and BlockEntity implementation? Looks like there's an NPE when rendering the screen, so I'd bet the problem is in your Screen implementation. The initialization of your BlockEntity doesn't tell us much. Also, did you make sure to register your Screen?

package com.an12854.leanmod.block.entity;

import com.an12854.leanmod.block.entity.ModBlockEntities;
import net.minecraft.core.BlockPos;
import net.minecraft.world.level.block.entity.BlockEntityType;
import net.minecraft.world.level.block.entity.SignBlockEntity;
import net.minecraft.world.level.block.state.BlockState;

public class ModSignBlockEntity extends SignBlockEntity {
    public ModSignBlockEntity(BlockPos p_155700_, BlockState p_155701_) {
        super (p_155700_, p_155701_);
    }

    @Override
    public BlockEntityType<?> getType() {
        return ModBlockEntities.SIGN_BLOCK_ENTITIES.get();
    }
}

None of the docs i found mention registering the screen so I would ask if you could point me in the right direction.

Ok I'm sorry, as I was responding I realized that registering screens is only relevant to MenuScreens, i.e. screens that connect to a menu implementation which sounds like this isn't the case. You can disregard registration of this screen as long as it's not connected to a menu (i.e. a class that extends AbstractContainerMenu)
