Fetch api success on tabris test program but production aab/apk is not work

Dear all,

I have a javascript file that is load from outside, and pass it to Module.execute
I have tested on tabris.js dev/test program, but the same code is not work on my built file.
Would you have any idea to check and solve the problem, thanks for your help.

I'm using tabris 3.9 and the sample code is pasted below:
```
const {contentView, TextView, Module} = require('tabris');
async function main() {
var url = 'https://some-valid.dummy/main.js';
var a = await fetch(url);
var b = await a.text();
try {
Module.execute(b, url);
}catch(e) {
}
}

main().catch(function(e) {
//nothing to do
new TextView({
text:"Error",
centerX: '0',
centerY: '0',
font: '36px',
}).appendTo(contentView);
})
```

cheers,

Alan (a.k.a. summer)
