Nodejs / Nginx服務器（AWS）/ Mysql / insert 502 Bad Gateway錯誤

Question

當我嘗試使用Mysql，AWS ElasticBeanstalk Nginx服務器插入一些文本時，

它有時會出現502 Bad Gateway的錯誤消息。

只插入大小寫錯誤（選擇，更新，刪除工作正常。）

如果我嘗試在localhost中插入，它運行得很好。

 <form action="/finance" method="post"> <div class="input-field col l12"> <input name="consult_name" type="text"> <input type="submit" value="send"> </div> </form> 

 router.post('/finance', function(req, res, next) { var consult_name = req.body.consult_name; console.log(consult_name); var sets = {consult_name : consult_name}; mysql.insert('insert into cider.cid_finance set ?', sets, function (err, data){ res.redirect('/finance'); }); });
