Hey there :slight_smile:

Are you using yarn or npm? There is an error message saying it found package-lock.json that is used by npm, but the build command is yarn.

Try changing your build command to npm ci

I am using yarn for this. I will try switching and see if that works. Thank you!

Ah ok, then there is no need to switch. How is your setup, where is the index.js file located? In the root of your project/repo?

Linux systems are case-sensitive, do the filename match or is it for example Index.js vs index.js?

Ya, I ended up figuring out just a little while ago. I had a couple of words spelt incorrectly, part of my format was incorrect, and names didn’t match up. With all of that fixed, it works now.

Thank you for your help.
