express js - GET request 404 not found when using sequelize - mysql

Question

I am using Sequelize and express.js in server development.
When I try to send GET request for route /files, an error shows:
{
"errors": {
"message": "Not Found",
"error": {
"status": 404
}
}
}
Folder structure
src
-models
-File.js
-routes
-api
-index.js
-files.js
-index.js
-app.js
-sequelize.js
package.json
I am trying to get ALL records from table files

Edit
In your /api/index.js file you have :
router.use('/files', require('./files'));
So the URL should be: http://localhost:3000/api/files/files
If you want to change the URL to: http://localhost:3000/api/files, in your files.js, you should change to :
router.get('/', (req,res) => // change "/files" to just "/"
Files.findAll()
.then(data => {
res.sendStatus(200)
})
.catch(err => console.log(err))
);
