Additional context

[Bug]

[tdurnford]

The Test in Web Chat blade in Azure is throwing an "ajaxExtended call failed" error in IE 11.

I tried navigating to https://webchat.botframework.com/embed/b/gemini?s=&b= to see if the error would replicated, and Web Chat threw a "'Promise' is undefined" error. We are probably missing a polyfill.

This will be addressed in 4.6/Ignite with https://github.com/microsoft/BotFramework-WebChat/pull/2315. Please reach out if this needs to be addressed sooner.

@cwhitten will Test in Web Chat be bumped to v4.6 after Ignite?

[cwhitten]

It will also need to be bumped

I'm going to close this issue since the PR is already in master bits.

This will be addressed in 4.6/Ignite with #2315. Please reach out if this needs to be addressed sooner.

@cwhitten Is it possible to pull this fix from NPM or elsewhere before Ignite?

[corinagum]

Please see our documentation on pointing to our MyGet feed for latest bits.

You can also follow the build directions on CONTRIBUTING.md to build your own temporary bundle of the latest bits.

Has this been addressed? We checked out chat in IE this morning and do not see any fix from when we deployed on Friday.

@lelgouacem, I checked out Internet Explorer and it looks like the embed page is not working. However since the error messages are different I am going to open a new issue to track further progress.
