We are using Vue 2 with Vue Facebook Login Component version 4.0.0

I had a look and it looks like some vendor generator functions (function*) related to async/await are not being transformed into ES5, which is required for IE 11 support. It's a configuration issue.

Try the new version: 4.0.1. This bug was reproducible in IE 11 using my demo. Per this commit the idea was to drop regenerator and save some KBs, but it seems transform-regenerator cannot be excluded because it then doesn't transform async/await functions. I re-included this plugin in Babel configuration to fix the issue, but it should be optimized later to transform only, excluding any polyfill code that bloats the package.
