TypeError: Cannot set property '_bitField' of undefined (Bluebird library)

Question

我正在使用蓝鸟2.x。

我正在调用包含在承诺中的 kafka。如果消息被发布，承诺就会得到解决。如果对kafka的调用失败，则promis被拒绝。

这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

有什么错误的建议吗？

Answer 1

第 98 行抛出的错误肯定是由于 Promise 之前没有使用 new。

node.js
