I have the following Javascript code:-

    const mainFunction = async (message) => {
      const templateData = {};
      templateData.name = message.firstName;
      templateData.email = message.emailAddress;  
      templateData.account = message.accountType;
      console.log("message::::", message);
      const userId = message.userId;
    
      const emailAddresses = [`${message.emailAddress}`];
      console.log("emailAddresses->", emailAddresses);
}

Logs:-

The problem is the constant emailAddress is coming as undefined but the value of the emailAddress attribute is present in the object message. I want to pass the dynamic value to this array of Strings but not working at all.

Please let me know why it is coming as undefined. Thanks
