I added static asset files script but it fails to upload

hi, i added a script on my scene (a custom image banner), i saw the script here

GitHub - shapespark/shapespark-viewer-api: JavaScript API for interacting with the Shapespark 3D scene.

and just followed the instruction but when i tried to upload it to test the scene, it fails, saying that it has invalid resource path.

I have standard Plan by the way.

thank you.

The Standard plan does not include the JavaScript customization option, you need the Plus plan for it.

What is the name of the file that you try to upload? Probably there is some problem with the name or format.
