vm error when calling getMaxMedia on oneironaut:endless_phial

[soup587]

seemingly caused by https://github.com/beholderface/oneironaut/blob/814378478c5e3d8c0c322b5543fadc1a3575b4c6/common/src/main/java/net/beholderface/oneironaut/item/BottomlessMediaItem.java#L52

unsure if this is on my end as i believe i'm calling the method in a standard way

applicable error:
java.lang.NullPointerException: Cannot invoke "com.mojang.datafixers.util.Pair.getSecond()" because the return value of "java.util.Map.get(Object)" is null
