Question

我的错误日志中出现以下错误。我不知道它何时发生，无法跟踪问题，因为它没有显示我的代码，而是显示node_module（mongoose）。如果您将想法发送到调试和修复，那将会很棒。

当我用Google搜索时，我发现它是在递归调用异步函数时发生的。但我没有通过异步调用进行任何递归调用或循环。

谢谢， Thavaprakash。 S上。

更新

请查看以下示例代码。

   var Promise = require('bluebird');
   var Business = require('business.model');
   var User = require('user.model');
   var userPromise = User.findOne({userId:121454}, function (err, user) {}).exec();
   Promise.all([userPromise]).then(function(results){ // here one promise passed, we may pass multiple promise in future
         var user = results[0];
         Business.findOne({bid:user.businessId},{}, function (err, busin) {
           if(err){
                  console.log(err);
                  res.status(500); 
                  return res.json({"code":500,"error": "internal server error"}) 
           } 

           res.status(200);
           return res.json({"name": busin.name}) 

         });
   });
