使用Twilio Node.js SDK v5.0.1无法发送WhatsApp模板消息求助

我正在使用Twilio的Node.js SDK v5.0.1向客户发送WhatsApp服务更新通知，但始终无法成功发送消息。

已具备的条件 #

• 已创建并通过WhatsApp审核的Twilio消息模板
• 状态为「在线」的WhatsApp企业ID及号码

模板详情 #

正文：Hi! Your {{2}} booking has been updated!
示例内容：BMW

按钮：https://[website]/view-booking?bookingId={{1}}

• 类型：Visit website
• 文本：View booking
• 示例内容：-wn54Cw5WO-G3QFUKHP_6dT6PEfApuiloZNoMdTuMZs%3D

尝试的两种方案 #

方案一 #

exports.sendSMS = async (phoneNumber) => {
  const accountSid = "";
  const authToken = "";
  const client = new twilio(accountSid, authToken);

  return await client.messages
    .create({
      contentSid: "[sid]",
      contentVariables: JSON.stringify({
        1: "BMW",
        2: "-wn54Cw5WO-G3QFUKHP_6dT6PEfApuiloZNoMdTuMZs%3D",
      }),
      from: "whatsapp:+[number]",
      to: `whatsapp:+${formatUKPhoneNumber(phoneNumber)}`,
    })
    .then((message) => {
      console.log(message);
      return message.sid;
    })
    .catch((e) => {
      console.log(`error0: ${e}`);
    });
};

报错信息：error0: Error: A text message body or media urls must be specified.

方案二 #

exports.sendSMS = async (phoneNumber) => {
  const accountSid = "";
  const authToken = "";
  const client = new twilio(accountSid, authToken);

  return await client.messages
    .create({
      body: "Hi! Your BMW booking has been updated!",
      from: "whatsapp:+[number]",
      to: `whatsapp:+${formatUKPhoneNumber(phoneNumber)}`,
    })
    .then((message) => {
      console.log(message);
      return message.sid;
    })
    .catch((e) => {
      console.log(`error0: ${e}`);
    });
};

问题现象：代码执行无报错，但Twilio日志显示消息发送失败（截图：）
