Are you trying to run a Node Project on basic hosting? Node requires a specific environment (set-up) and can not just be uploaded to the site root of a basic hosting package. The package needs to support NodeJS.
I was going to say the same thing @Cheese mentioned. Looks like a node site with non compatible hosting or not set up right on the server. I don’t think go daddy supports node.js.
Yes, GoDaddy does support Node.js, but the level of support depends on the hosting plan you choose. If you're using shared hosting, you might face limitations, and you may need to upgrade to a VPS or dedicated server for full Node.js functionality. Some users have managed to run Node.js on shared hosting by manually installing it and configuring their environment.
If you're looking for a straightforward setup, GoDaddy's VPS or dedicated hosting would be the best option. You can check out more details on GoDaddy's blog about how they use Node.js.
Because it hasn’t been mentioned yet, make sure you delete all those files from the public_html. If you’re using a database or have any other passwords/api keys in your project, reset them as you unintentionally would have leaked them all.
