[1.11] NullPointer on trying to get a list of dimensions.

I am trying to make my mod create configurations for every dimension that is registered. However, I'm getting a null pointer exception and have tried many times in vain to fix it. Here is the code:

  

public static void loadAll() {
        //Dimensions
        Integer[] ids = DimensionManager.getStaticDimensionIDs();

        for (int id : ids) {
            WorldProvider dimension = DimensionManager.getProvider(id); //NullPointer

            String modId = ModIdentification.idFromObject(dimension);

            File file = new File(EnviroMineRevived.configDir, modId.toLowerCase() + "\\dimension.json");

            DimensionProperties.base.load(file);
        }
  ...
    }

 

I then call this method in my post-init method. It however throws a null pointer which leads me to believe that none of the dimensions are registered by then. Where should I be calling this?

 

If you need more code just ask. Following is the error:

You first need to get all DimensionTypes: DimensionType.values(). Then for each one you need to get all it's dimension IDs using DimensionManager.getDimensions(DimensionType).

In one operation: 

int[] dimensions = Stream.of(DimensionType.values()).flatMapToInt(t -> Stream.of(DimensionManager.getDimensions(t))).distinct();

I'm still not having any luck. Any other ideas? There is a null pointer on the same method as last time. :/

Spoiler

The method with the exception: 


public static void loadAll() {
        //Dimensions
        List<Integer> ids = EnviroUtils.getDimensionIds();

        for (int id : ids) {
            WorldProvider dimension = DimensionManager.getProvider(id); //Null pointer

            String modId = ModIdentification.idFromObject(dimension);

            //File file = new File(EM_ConfigHandler.loadedProfile + EM_ConfigHandler.customPath + EnviroUtils.SafeFilename(modID) + ".cfg");
            File file = new File(EnviroMineRevived.configDir, modId.toLowerCase() + "\\dimension.json");

            DimensionProperties.base.load(file);
        }
  ...
}

 

The method I use to get all the ids: 


...
  
public static List<Integer> getDimensionIds() {
        List<Integer> ids = Lists.newArrayList();

        DimensionType[] types = DimensionType.values();

        for (DimensionType type : types) {
            int[] idArray = DimensionManager.getDimensions(type);

            for (int id : idArray) {
                ids.add(id);
            }
        }

        return ids;
    }

...
