WAB error on IE11

rajujee — Mon, 25 Feb 2019 17:50:30 GMT

Hello experts,

My WAB application is not working with latest WAB Developer Edition (v2.11) in IE11 only. It shows continuous loading size in the browser.

I get error on init.js

Error: abort("Assertion failed: no binaryen method succeeded."). Build with -s ASSERTIONS=1 for more info.

I am using a custom widget that requires me to use WAB Developer Edition.

PLEASE HELP!

Could be related to a IE security update. See this thread:

Raju,

Is The application running in compatibility mode in IE?

Thanks Rob for always being helpful. Application is not running on compatibility mode.

Do you suggest to implement following code as a work around ?

IE11 support broken due to emscripten issue · Issue #96 · medialize/sass.js · GitHub

if (!self.crypto) {
self.crypto = {
getRandomValues: function(array) {
for (var i = 0, l = array.length; i < l; i++) {
array = Math.floor(Math.random() * 256
}
return array;
}
};
}

No. I am not having an issue with WAB 2.11 in IE 11... So I am not sure what you issue is if your app is running in Edge mode and not compatability mode.

I am also getting this problem. Same version of IE and WAB. Was there any solution?

Thanks.
