I have a project uses Express and react, Everything was working fine,

I didn't make any changes to the code suddenly it starts to give this error.

In the previous days, I have upgraded node from 10.15.0 to 12.x and added Axios.

I tested after those changes and it works. now it does not, what this mean??

Answer 1

I found the I have mistakenly typed

import response from { 'express' }

I found that this problem happens when you try to call backEnd stuff in your frontEnd. when I delete that line problem solved.

Edit: it turns out that I didn't type the import statement because I used the word response as a variable name, it was automatically imported. I'm not sure if the import was from React itself or another VS code auto-completion extension.
