'error' [TypeError: null is not an object (evaluating 'app.keyWindow')]

[bnowacky]

Using Nativescript-vue. 4.2.3

In our main.js file, we're calling:

const AdvancedWebView = require("nativescript-advanced-webview");
AdvancedWebView.init();

in our vue component, we're calling:

var opts = {
        url: 'https://google.com',
};

try {
      AdvancedWebView.openAdvancedUrl(opts);
 } catch(err) {
      console.log('error', err);
 }

Unfortunately though, we are getting the error noted above: 'error' [TypeError: null is not an object (evaluating 'app.keyWindow')]

We know the openAdvancedURL() method is being called, because if we leave the opts.url blank, we get the appropriate error.

any ideas on what we're missing?

Only instance of keyWindow in repo here https://github.com/bradmartin/nativescript-advanced-webview/blob/92ab8d454ec1439d86f9a7f6c3581bc31bd9ac7f/src/advanced-webview.ios.ts#L57 not sure why that happens. Leaving for reference 👍

Yup... Saw that as well, and we logged values to see where we died before that.

console.log('utils', utils);
console.log('utils.ios', utils.ios);
console.log('thewholething', utils.ios.getter(UIApplication, UIApplication.sharedApplication));

utils.ios.getter() returns null , so app is null, which is why it's erring I believe.

FWIW, we're running on iOS 12. but we've tried on 11 as well with no luck. Not something you've experienced before?

Never seen that and demo app runs fine. I added a check on the keyWindow and published 3.0.2, see if that helps clean things up and let me know.
