Issue #3895: Opusscript Error: cannot convert "null" to int
Created: 2020-03-04T14:00:24Z
Please describe the problem you are having in as much detail as possible:
After updating discord.js to version 12, when bot try to join into the voice channel, the code throws the error "cannot convert null to 'int'" in opusscript. I checked it works properly on @discordjs/opus, but it doesn't sounds clear.
Include a reproducible code sample here, if possible:
let commandJoin = {
    cmd: /\bjoin\b|\bj\b/i,
    async exec(_client, msg, _param) {
        let voiceChannel = msg.member.voice.channel;
        if (msg.guild.me.voice.channel) {
            if (msg.guild.me.voice.channel.equals(voiceChannel)) {
                await send(msg.channel, new Discord.MessageEmbed()
                    .setTitle(':notes: Already joined!')
                );
            } else {
                await voiceChannel.join();
            }
        } else {
            await voiceChannel.join();
        }
    }
};
Further details:

discord.js version: 12.0.1
Node.js version: 12.16.1
Operating system: Windows 10
Priority this issue should have – please be realistic and elaborate if possible:
