Thanks for reporting. Definitely need to get this fixed.

@rwjblue I've also just been hit by this issue in our app. Object.fromEntries is not polyfilled by @babel/polyfill. This is because @babel/polyfill (now deprecated) ships with core-js 2.x (2.x is deprecated) and Object.fromEntries only ships from 3.x.

I'm happy to try and put together a PR if it's just a matter of switching out dependencies, and tweaking the build pipeline?

@patocallaghan - I haven't really dug into this so I'm not sure if that is all that we need to do, but it seems reasonable to me and help (even just researching) is absolutely welcome.

Okay thanks, I'll see if I can dig in at some stage this week

Logged https://github.com/babel/broccoli-babel-transpiler/issues/197 as @babel/polyfill is used by ember-cli-babel and broccoli-babel-transpiler

https://github.com/babel/broccoli-babel-transpiler/pull/191 removed the polyfill from broccoli-babel-transpiler already, just hasn't been released yet (it'll be 8.0.0).
