Try this.

    if (!channel) return console.error("The channel does not exist!");
    channel.join().then(connection => {
        console.log("Successfully connected.");

You have to specify a guild ID and voice adapter creator

joinVoiceChannel({
  channelId: "channelId",
  guildId: "guildId",
  adapterCreator: client.guilds.cache.get("guildId").voiceAdapterCreator
})
