I can't launch the application on my server, but it works fine locally.

[alayouv]

After running the npm install and npm run build commands, I end up with a build folder at the root. I tell the server (via nodeJs setup on o2switch) that the application's startup file is "index.js," which is located in the build folder. But I get a series of errors that make me doubt the compatibility of the js-potential files.
I want to point out that I can successfully launch the application locally with the npm run dev command.
Thank you.

Here's an example of an error:

/home/ctoy8478/appnode1/index.js:1
import { handler } from './handler.js';
