express-sanitizer | An express.js middleware for node-validator | Runtime Evironment library

I have hosted my MERN app on Heroku , but whenever I implement helmet in app.js file it's causing this issue.

I am trying to deploy a application to heroku but it keeps showing this error errno 1.
My error

I am trying to add isLoggedIn middleware that uses isAuthenticated to my small app but seems that it is not working.
By removing the middleware, the Login page works fine and redirects, but if I add it to the admin page(where the login redirects), the console.log(isAuthenticated()) is always false.

It seems that something happens with the credentials after adding the middleare and they cannot be checked.
I bet it is something tiny but after hours I couldn't figure it out. The code of the app.js is the one below:

There are several answers for this question, but they're all several years old and no longer relevant/safe to use.

Since EJS is rendered as html in the browser, there's no way to inspect it in the browser dev tools

The EJS.co site says that the errors/logs should show in the terminal just like node errors, but that's not the reality for me, somehow.

I used the command npx express-generator to bootstrap my project, and I'm wondering if there isn't a debugger of some kind in there that is overriding how EJS is supposed to send errors?

I say this because when EJS has an error, the only thing my terminal shows is something like GET /users/dashboard 500 26.5 ms with nothing else. And then of course the browser shows the default message for 500 errors, which isn't helpful.

I'll throw in my app.js in case someone smarter than me can see the issue there:

I've been looking and trying to figure this out for two days now, and the only real mention of it that I can find is an old issue report on version 1.1.0 which was closed without resolution: https://github.com/expressjs/multer/issues/338

I'm using Node.js SDK and Express framework, with Cloudinary as my image host.

This is just a project for a class, but it's important that I know how to get this to work for future projects.

I was working on a CRUD application which allows uploading images also using the Cloudinary package. I am using Node.js, express and MongoDB. After implementing the Cloudinary upload part my app suddenly got crashed. I don't know what happened! I reverted back the changes but the problem is still occurring. I am getting the error

I'm currently a student studying Web Development with Node. I recently was reviewing RESTful routes. I was building a blog site to do so. I was setting up a route to show a specific blog "/blogs/:id" which lets you see all the contents of a blog. Here's the route:

Solved!

The initial problem: I'm using TinyMCE for a text editor. Right now, I just have the default plugins applied. It appears that 'autolink' is one of those, as it turned a link into an 'a' tag. The problem I'm having is that it's not giving the 'a' tag an href. I tried applying the 'link' plugin, but it's giving me the same problem. It creates blue, underlined text in the form of an 'a' tag, but omits any kind of href.

How can I get this to work correctly?

I'm running on a Windows computer in Chrome, though I tried it in Microsoft Edge just to see if that did anything and it didn't.

This was my initial configuration, copy-pasted form their website.

This is my most recent configuration. It's formed from a combination of a codepen I found and a few things I've tried.

Solution: I tried a different rich text editor to see if that would help and it was doing the same thing. After a little more digging, I found that express-sanitizer was the culprit.

I am currently using MySQL for the db instead of the popular mongodb, since that is the case there isn't much documentation out there as far as architecture and getting set up. This is my current structure
