Node problem when uploading to Useberry

Hello everybody, hope somebody can help me with a node problem I’m having. I linked up all my screens, but when I go to upload it to Useberry I keep getting an error message that says the prototype doesn’t have a starting point.

But as you can see from the screenshot of my project, there’s one right there. Is there something I’m missing or not doing right? If anybody has any advice I’d really appreciate it. Thank you.

It seems there might be an issue with the node package or the upload process to Useberry. Double-check the installation and configuration, ensure you have the latest version, and consult the package documentation or support for troubleshooting.
