Posted 10 hours ago10 hr [main/ERROR]:Failed reading REFMAP JSON from : java.lang.NullPointerException Cannot invoke "org.spongepowered.asm.mixin.refmap.ReferenceMapper.setResourceName(String)" because "mapper" is nullthis is the error message i keep getting when trying to launch minecraft from the launcher with my mods but i just can't figure out what this error message means. i'm new to making mod packs but i have tried making 3 separate mod packs with different mods but i still run into this issue and i am starting to think there might be a conflict between 2 different mods but again i have no idea since this is the only error message i get. any idea's?
