Describe the bug

After 4.1.7 - polyfill fixes broke webpack bundling
Commit here: a20a44c#diff-a4cb641e4ac7086ddd5b5af0968c47f4
Webpack cannot 'see' the require therefore leaves it in tries to look in node_modules

To Reproduce

Steps to reproduce the behavior:

1. Bundle app using bot framework with webpack
2. Run bundle (tries to load form-data from node_modules), throws module error

Expected behavior

Not to throw module error and form-data, node-fetch to be included in the bundle

Additional context

Webpack used for bundling code on lambdas due to size limit

@JuanAr Any update on this?

Hi @cleemullins,

We were able to reproduce this issue, and we find out that this was failing because the botframework-connector library uses a dynamic import (which are set in execution time), but Webpack uses the imports generated in compile time.

To solve this issue we are investigating two possible approaches. The first one would be adding magic comments to the import statement, and the second one is changing the way we are doing the imports.

@ballwood, you shouldn't need the botframework-connector library unless you're hooking a browser-hosted bot to the Bot Framework channel service. Can you explain your scenario a little further?
