Hi, I'm trying to create custom datapack support for my 5x5 workbench. But when I add a json file to: 'resourses > data > jobsplus (modid) > custom_recipes' and I load a world, it says I need to try safe mode and gives me te following error:

P.S. when I remove the file in 'custom_recipes' or when I comment out the line in 'EventAddReloadListener': 

event.addListener(ModRecipeManager.instance);

The world loads without a problem.

 

Spoiler

public static final ModRecipeManager instance = new ModRecipeManager(); // What is the value of GSON here?
private static final Gson GSON = new GsonBuilder().setPrettyPrinting().disableHtmlEscaping().create();

 

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.

Thank you @warjort. Moving GSON to the top resolved the issue.

New ModRecipeManager class: 

public class ModRecipeManager extends SimpleJsonResourceReloadListener {

	private static final Gson GSON = new GsonBuilder().setPrettyPrinting().disableHtmlEscaping().create();
    public static final ModRecipeManager instance = new ModRecipeManager();

    public ModRecipeManager() {
        super(GSON, "custom_recipes");
    }

    @Override
    protected void apply(Map<ResourceLocation, JsonElement> jsonElementMap, ResourceManager p_10794_, ProfilerFiller p_10795_) {
    }
}
