流星onCreateUser方法错误

Question

我希望用户注册该网站后将其发送给用户。 但是，我不断收到错误：

I20150729-22:44:52.253(-4)? Exception while invoking method 'entryCreateUser' Error: Match error: Expected string, got undefined in field [0]

这是我的onCreateUser方法：

Accounts.onCreateUser(function(options, user) {

        var userEmail = user.email
        var emailSubject = "Welcome to Company!";
        var emailBody = "SUP";

         Meteor.call('sendEmail',
                        userEmail,
                        '',
                        '',
                        emailSubject,
                        emailBody
                      );
    });

有人可以帮忙吗？

谢谢！！

您将要查看收集挂钩包，以在创建用户文档后立即触发代码。 这对于在存储用户文档之前修改用户文档本身也很有用。 当然，它可以用于任何集合，而不仅仅是用户。
