Hello everyone, Im trying to parse a String (json) to NBT with JsonToNBT#getTagFromJson but its apparently broken:
  

 @Override
    public void fromBytes(ByteBuf buf) {
        try {
            String received = new String(buf.array());
            NBTTagCompound nbt = JsonToNBT.getTagFromJson(received);
            this.mana = new ManaData(nbt);
        }catch (Exception ex){
            ex.printStackTrace();
        }
    }

Look at the Intellij Idea debugger h5cUkUD.png

This is a perfect string made with NBTDataCompoud#toString()

This is not what these functions are intended for. If you want to send NBT through packets (please don't, unless you have a very good reason to) you need to use ByteBufUtils.writeTag and ByteBufUtils.readTag.

thanks a lot you are saving my poor life
