I have a webapp made with react express mongo running in Heorku, auto deployed by branches, my last deploy/build was working correctly, two days ave passed and I made minor changes to README.md (added mermaid gitgraph via github editor) and it suddenly crashed tis is the heroku log:

Server now listening on PORT 28845! /app/node_modules/mongodb/lib/core/uri_parser.js:580 return callback(new MongoParseError('URI malformed, cannot be parsed')); ^

MongoParseError: URI malformed, cannot be parsed at parseConnectionString (/app/node_modules/mongodb/lib/core/uri_parser.js:580:21) at QueryReqWrap.callback (/app/node_modules/mongodb/lib/core/uri_parser.js:127:7) at QueryReqWrap.onresolve [as oncomplete] (node:internal/dns/callback_resolver:49:10)

Node.js v19.1.0

[email protected] start:dev concurrently "nodemon --ignore 'client/*'" "npm run client"

sh: 1: concurrently: not found Process exited with status 127

my code for the server:

const express = require("express");
require('dotenv').config()
const mongoose = require("mongoose");
const routes = require("./routes");
const app = express();
const PORT = process.env.PORT || 3001;
// const http = require('http').Server(app);

// Define middleware here
app.use(express.urlencoded({ extended: true }));
app.use(express.json());

if (process.env.NODE_ENV === "production") {
  app.use(express.static("client/build"));
}
app.use(routes);

// Connect to Mongo DB
mongoose.connect(process.env.MONGODB_URI || "mongodb://localhost/cmx", { useNewUrlParser: true, useUnifiedTopology: true, useFindAndModify: false, useCreateIndex: true });

// Start the API server
const server = app.listen(PORT, function() {
  console.log(`CMX ==> API Server now listening on PORT ${PORT}!`);
});

const io = require('socket.io')(server, {transports: ['polling', 'websocket']}); 
io.on("connection", (socket) => {
  app.set("socketId", socket.id)
    console.log("New client connected",socket.id);
  socket.on("disconnect", () => {
    console.log("Client disconnected", socket.id);
  });
});

and in ENV in heroku/config have:

MONGODB_URI=mongodb srv://<user>:<password>@cluster<clustername>.mongodb.net/heroku_<clustername>?authSource=admin&replicaSet=atlas-48xk7w-shard-0&readPreference=primary&appname=MongoDB Compass&ssl=true

Consolelog to: MONGODB_URI result in the exact same string My other branches deployed result in te same error when i've tried to push a new commit Some of my tests include making a commit with jusy one extra space an result in the same error I made a rollback to my prod branch and it run without problems The application is running without problems in local

CodePudding user response：

The problem was that heroku updated the node version that I was using, and was not compatible with the version of mongoose used, updating dependencies solved the problem
