Known issue, need contributors in PrismarineJS/minecraft-data#948

[deinemuttermitbutter]

hi, uhm i had the same issue ... i just edited the compiler.js of protodef to pass every array trough, no matter how big it is...
works for me...

file: /node_modules/protodef/src/compiler.js
the change i did: https://github.com/deinemuttermitbutter/node-protodef/blob/2936e87f8f7636e950fa07ae5374ffbadda0d26a/src/compiler.js#L110

as i said before: as long as it works ... its fine

[extremeheat]

No, it doesn't work. That error being hit is not being hit because the array is big but as a sanity check as invalid data is being read. The protocol spec in minecraft-data is wrong and needs to be fixed. For that it is waiting on contributors in PrismarineJS/minecraft-data#948
