Describe your issue

A call to setValue<T extends Internal.Comparable<T>, V extends T>(arg0: Internal.Property_<T>, arg1: V): S; will almost always crash as arg1: V is resolved to java.lang.Object at runtime, while the JS primitive types are considered to be different types.

Example code (not complete):

let level = blockEntity.blockState.getValue($ComposterBlock.LEVEL)
blockEntity.blockState = blockEntity.blockState.setValue($ComposterBlock.LEVEL, level + 1)
