为什么 startWithPrefix 在 discord.js v13 中不起作用？

Question

I want to update my Truth Or dare bot discord.js v12 to v13. now I faced some problems when I use ping pong its works fine but when I wanna do something with my prefix it gives me this error. I've never used discord.js v13 but one of my friends says that discord.js v12 will be disappear and discord will deactivate those bots

The issue is not with your prefix, it is due to you sending embeds incorrectly.

You are currently sending embeds for example:

    message.channel.send(new Discord.MessageEmbed()
      .setColor('#7B00F7')
      .setURL('https://discord.com/api/oauth2/authorize?client_id=874488895037911041&permissions=259846043712&scope=bot')
      .setTitle("Dare")
      .setDescription(dare))

A correct way to send embeds would be something like:

    message.channel.send(
        { embeds: [new Discord.MessageEmbed()
          .setColor('#7B00F7')
          .setURL('https://discord.com/api/oauth2/authorize? 
    client_id=874488895037911041&permissions=259846043712&scope=bot')
          .setTitle("Dare")
          .setDescription(dare)]
        }
