Hi,
Encapsulation doesn't work when the object has properties that throw errors. These properties should be ignored.
To reproduce, open this HTML file in browser.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script type="module">
import { Typeson } from "https://cdn.jsdelivr.net/npm/typeson@7.0.1/dist/typeson.esm.js";
new Typeson().encapsulate(Object.getPrototypeOf(navigator));
</script>
<script type="module">
import { Typeson } from "https://cdn.jsdelivr.net/npm/typeson@7.0.1/dist/typeson.esm.js";
const foo = {};
Object.defineProperty(foo, "bar", {
enumerable: true,
get() { throw Error("baz"); },
});
console.log(new Typeson().encapsulate(foo));
</script>
</head>
</html>This two errors are logged in console of Firefox:
Uncaught TypeError: 'get permissions' called on an object that does not implement interface Navigator.
