getResourceById throwing an exception

[MrSpomg]

Hello! I am currently using your awesome api for Spigot for a project. However, when trying to get a resource (by ID) it gives me this error:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.rangeCheck(ArrayList.java:657) at java.util.ArrayList.get(ArrayList.java:433) at be.maximvdw.spigotsite.jsoup.select.Elements.get(Elements.java:523) at be.maximvdw.spigotsite.resource.SpigotResourceManager.getResourceById(SpigotResourceManager.java:52) at be.maximvdw.spigotsite.resource.SpigotResourceManager.getResourceById(SpigotResourceManager.java:30) at me.spomg.system.bot.bridge.spigotsite.Spigot.getResources(Spigot.java:75) at me.spomg.system.bot.bridge.spigotsite.schedulers.NewBuyersScheduler.run(NewBuyersScheduler.java:36) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748)

The code used:
`public Set getResources() {
final Set value = new HashSet<>();

try {
    for (String id : bot.getConfigFetcher().getStrings("resources")) {
        value.add(getResourceManager().getResourceById(Integer.parseInt(id)));
    }
} catch (ConnectionFailedException ex) {
    LogHelper.logException("An error occurred while getting resources.", ex);
    return null;
}

return value;

}`
I also tryed by using the method with a normal ID (and not using the config).
How do I fix this? Thanks!

This gets bugged, but I made it work using getResourcesByUser

I have that problem too
