Hi, I’m trying to deploy an app React app created with create-react-app. It keeps failing after it tries to run the build command.

See log below. It seems like it not able to find the .svg file even though it is there. Letter casing is correct and it works locally.

Anybody know why it is Failing even though it’s working locally. I’m on a MAC OS.

Thanks in advance for your help!

Howdy,

it’s definitely related to us not being able to find the file

If it’s not case (you are sure? that is the cause of the problem 99.99% of the time…) is it maybe the path?

just in case… (that was a terrible joke)

import {App} from ‘./app’;

I’ve tried to add the node and npm version I’m using in a netlify.toml file but it still doesn’t work.

Uploading the build folder works fine

I found the issue. For whatever reason, git was keeping track of app.js as App.js . Thus, the file uploaded via Github to Netlify was nammed App.js .

To solve this I did: git rm -r --cached src/App.js , git add src/app.js and it worked.
