I am asking here because I do not know how the new JSON format works and have found no documentation on it at all.
I have tried to use this command:
{"layers"\:[{"block"\:"minecraft\:air","height"\:1}],"biome"\:"minecraft\:the_void"}
but it won't work.
{"layers"\:[{"block"\:"minecraft\:air","height"\:1}],"biome"\:"minecraft\:the_void"}
but it does not work
