打字稿错误：类型“Message<TextableChannel>”不可分配给类型“void”

Question

    TSError: Ô¿» Unable to compile TypeScript:
    src/commands/general/Vote.ts:26:7 - error TS2322: Type 'Message<TextableChannel>' is not assignable to type 'void'.

  async execute(client: IMClient, message: Message, _args: Array<string>): Promise<void> {
    try {
      client.bot
      .createMessage((await message.author.getDMChannel()).id, {
        embed: CreateEmptyEmbed(client, Color.Standard, message.guildID ? message.guildID : "")
          .setTitle("Hello! ?")
          .setDescription(`Thanks for your interest in voting for me!`)
          .addField("Vote! ?", "If you are feeling really kind, you can vote for our bot here in order to help support us [here](te)"),
        content: "Need support? Join our support Discord ",
      })} catch(err) {
        return await client.bot.createMessage(message.channel.id, {
          embed: CreateEmptyEmbed(client, Color.Warning, message.guildID ? message.guildID : "")
            .setTitle("I couldn't send you a direct message!")
            .setDescription("Have you got recieving messages from none friended people enabled?"),
        });
      };

我有一个打字稿错误。

这个错误是什么意思？我该如何修复它？
