express-fileupload | Simple express file upload middleware | Runtime Evironment library

I have some user info that I want to save in mongodb database. I checked API post with postman by filling in some form-data fields in body. Simple data such as name or email, simple Strings work perfectly, but when I changed code(in controller.js file) so I can also get image file, it throws this generic error: "Cannot POST /api/users". The code seems fine to me but something's missing and can't figure it out.

server.js file:

I am building a backend for a project of mine. I currently have my server/routers/controllers setup for the backend. I am creating the profile section of my project. I have profile pictures that I am trying to save when a user submits his profile. One part of of the profile is the profile picture. I am currently sending the profile picture from the react frontend to the express backend. The file is being sent correctly, but I am having issues saving the images on my local server when it is submitted.

I did some debugging & found out image is present during validation, but it is not present when it is sent to request handler to store the db object. Please check this image of debugging output

There is also a strange error in the DB. title, body & image path is getting inserted two times inside DB. I deleted the old stuff & tried it again & again. But still noticed, for one insertion using '/posts/new' page: two same objects is getting stored in mongodb. Image attached from Mongo DB compass

Here is the project flow: The request object with the image is picked from '/posts/new' page, validated in the validation middleware, if title & image are present: it will be sent to the request handler app.post('/posts/store', storePostController); which will store the image using path & it will store a mongo db document which contains title, body & image path inside the DB.

The code for the following is given below: 1) createPost.ejs

I was Trying to make a shopping cart. i was making admin panel in which i need to submit the image for adding product. After creating the Form

I am building a small image upload application using node js. I have imported proper packages, have run the methods as it has to be. Image is being retrieved as multipart-form data. But inside the mv() function I am getting the following error.

I'm working on my CRUD app what I`m trying to do is to download files from MySql Nodejs server. Here the steps I've achieved so far:

• I create the below function to query MySql database to find the id=179(just a random id). The function is inside a file called userContoller.js.

req.files keeps returning undefined. I've tried connect-multiparty, body-parser, and express-fileupload. How do I make it work using express-fileupload and not multer?
