I’m begun in fabric modding and i want for my mod to load a resource pack when the mod is loaded.
Then, i found in the fabric api a code, i took for my mod here.

package com.name.exampleMod;

import java.util.Collection;
import java.util.function.Predicate;
import java.lang.Iterable;
import java.io.InputStream;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import net.fabricmc.api.ModInitializer;
import net.fabricmc.fabric.api.resource.ResourceManagerHelper;
import net.fabricmc.fabric.api.resource.SimpleSynchronousResourceReloadListener;
import net.minecraft.resource.ResourceManager;
import net.minecraft.resource.ResourceType;
import net.minecraft.util.Identifier;

public class Concatenation implements ModInitializer {
    // This logger is used to write text to the console and the log file.
    // It is considered best practice to use your mod id as the logger's name.
    // That way, it's clear which mod wrote info, warnings, and errors.
    public static final String MOD_ID = "exampleMod";
    public static final Logger LOGGER = LoggerFactory.getLogger(MOD_ID);
    
    @Override
    public void onInitialize() {
        // This code runs as soon as Minecraft is in a mod-load-ready state.
        // However, some things (like resources) may still be uninitialized.
        // Proceed with mild caution.

        LOGGER.info("HOI!!! fabric World !!!");
        
                
                
        ResourceManagerHelper.get(ResourceType.SERVER_DATA).registerReloadListener(new SimpleSynchronousResourceReloadListener() {
            @Override
            public Identifier getFabricId() {
                return new Identifier("tutorial", "my_resources");
            }
 
            @Override
            public void reload(ResourceManager manager) {
                // Clear Caches Here

                for(Identifier id : manager.findResources("my_resource_folder", path -> path.endsWith(".json"))) {
                    try(InputStream stream = manager.getResource(id).getInputStream()) {
                        // Consume the stream however you want, medium, rare, or well done.
                    } catch(Exception e) {
                        LOGGER.error("Error occurred while loading resource json" + id.toString(), e);
                    }
                }
            }
        });
}

    public static String getModId() {
        return MOD_ID;
    }

    public static Logger getLogger() {
        return LOGGER;
    }
            
            
}

But i don’t know why i got this error “Can only iterate over an array or an instance of java.lang.Iterable” when i took the code from the documentation.

Here the link of the doc’s code : https://fabricmc.net/wiki/tutorial:custom_resources

When i got the error i tried to see where is the problem. And in my researches i saw that the problem can come from this function “.findRessource()”. The same function come from the minecraft api and this needs for argument a Predicate and the documentation tell the function needs for argument a Predicate. But, i don’t know if this is it.

Can i have some help ? And sorry for my bad english.
