var version = "1.0";

console.clear();

This returns a string type:

var answer = window.prompt(msg, "");

It seems that GraalVM does not convert string to int types in the array index - modelList[answer]

So you need to convert answer to an int first:

answer = parseInt(answer);

This is a GraalVM thing, so there's nothing I can do about it. GraalVM support is experimental and will require some changes in one's JS code.

I think we should make it clearer that GraalVM is not meant to be one-to-one compatible with existing scripts nor current API.

Well, I tried to in the forum post (https://forum.archimatetool.com/index.php?topic=951.0). I imagine that even if we made this clearer in the wiki I'm not sure people will read it.

I did read that though. But was clueless on how to resolve this. It is working properly now. Thank you.

It might be worth displaying a red message on the Script Console each time a script is ran using GraalVM ;-)
