Question

我在NodeChef上运行的Parse Server上使用以下功能：

var sendMail = function(sendMailData) {
    return Parse.Cloud.httpRequest({
        method: 'POST',
        url: 'https://api.sparkpost.com/api/v1/transmissions',
        body: {
            content: {
                from: 'noreply@domain.com',
                subject: sendMailData.subject,
                template_id: sendMailData.templateId,
            },
            substitution_data: sendMailData.substitution_data,
            recipients: sendMailData.recipients
        },
        headers: {
            'Authorization': 'AUTHKEY',
            'Content-Type': 'application/json'
        }
    });
}

sendMail(defaultSendMailData).then(function(okresp) {
    var attemptedSend = false;
    if (request.user.get('config')) {
        var userConfig = request.user.get('config')
        if (userConfig.copyPrescription === true) {
            attemptedSend = true;
            sendMail(defaultSendMailData).then(function(okresp) {
                var attemptedSend = false;
                if (request.user.get('config')) {
                    var userConfig = request.user.get('config')
                    if (userConfig.copyPrescription === true) {
                        attemptedSend = true;
                        sendMail(copyPrescriptionSendMailData).then(function(okresp) {
                            console.log('Woohoo! You just sent your first mailing 1!');
                            response.success("Great! Your program has been sent!");
                        }, function(errresp) {
                            console.log('Whoops! Something went wrong 1');
                            console.log(errresp);
                            response.error(errresp);
                        });
                    }
                };
                console.log('Woohoo! You just sent your first mailing 2!');
                if (!attemptedSend) {
                    response.success("Great! Your program has been sent!");
                }
            }, function(errresp) {
                console.log('Whoops! Something went wrong 2');
                console.log(errresp);
                response.error(errresp);
            });
        });
    }
});

并收到以下错误：

Error: Can't set headers after they are sent.

虽然功能似乎有效，但我关注这个错误及其来源。我不相信Parse.com就是这种情况（我使用的是完全相同的代码）。此错误未显示在我的Parse.com日志中。任何有关我的Parse Server生产部署的帮助实际上都是这次（第3次尝试！）将非常感激。

感谢上述所有评论，试图解决此问题。 Node Chef联系过我，他说：

该错误是由星期六2.2.17解析服务器更新引起的。

其他用户注意到并报告了它，我们不得不回滚   更新。

目前，自动更新已关闭，您可以手动更新   从服务器设置随时更新服务器＆gt;运行时设置   在您确信新版本适用于您的应用后。

回滚有效，我现在没有任何错误。
