code: "PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR" in nodeJs MySQL

Question

I have this issue since I uploaded my code on hosting panel, my Database is different server and API is a different server The error is code: "PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR", fatal: false}

it is working for some time but after calling another API then an error is occurring. Here is my code

app.js

var mysql      = require('mysql');

var connection = mysql.createConnection({
  host     : 'xx.xx.xx.xx',
  user     : 'abc',
  password : '123',
  database : 'XYZ',
 });

connection.connect(function(err) {
    if (err) {
      console.error('error connecting: ' + err.stack);
      return;
    }
   console.log('connected as id ' + connection.threadId);
  });

Here is the controller user.js

var mysql      = require('mysql');
   var connection = mysql.createConnection({
      host     : 'xx.xx.xx.xx',
      user     : 'abc',
      password : '123',
      database : 'XYZ',
     })

This is one code snippet of my API.

exports.getLandLord =(req, res, next)=>{
    var sql =`SELECT *FROM  registrations`;
       connection.query(sql, function(error, result, field){
        if(error){
            return res.status(201).json({message:error, status:402, success:false})
        }
        else
        if(result.length>0){
            res.status(200).json({message:"Land Loard List", status:200, success:true, 
          users:result,})
        }
        else
        res.status(200).json({message:"No Record Found ", status:402, success:false, users:result})
    })


}

I tried googling but I was not able to make it fix.

Have you tried restarting it? Or kill all the node processes then start it again — FanoFN, Jan 29 '20 at 07:19
