Question

我正在使用bluebird 2.x。

我打电话给承诺里面的kafka。如果消息已发布，则承诺将得到解决。如果对卡夫卡的调用失败，则会拒绝承诺。

以下是导致错误的代码段 -

redis.get(something)
.then(function() { 
            return Promise(function(resolve, reject) { // This is Line 98 in the stacktrace
                producer.send([
                    {
                        topic : "Ganga",
                        messages : [JSON.stringify({// some object})]
                    }
                ], function(err, data) {
                    if(err) {
                        logger.error("Error")
                        logger.error(err);
                        reject(err);
                        return;
                    }
                    resolve(data);
                })
            });
        })

堆栈跟踪如下

关于可能出错的任何建议？

错误在第98行引发它肯定是因为在Promise之前没有使用new。
