Meteor 1.8 oauth1 update broke my package - TypeError: OAuth1Binding is not a constructor

Hi Meteor community,

I’m stuck trying to workaround a breaking change in Meteor 1.8 when the oauth1 atmosphere package was updated to ES2015+. It doesn’t appear that my code stored under /server (rather than /imports) can create an instance of an OAuth1Binding anymore.

Any idea why?
Is there a workaround?

The error I get is: OAuth1Binding is not a constructor.
I’ve tried adding "import {OAuth1Binding} from ‘meteor/oauth1’; to the top of the file without any success.
FWIW, when I try moving this code under /imports/startup/server it fails for other reasons.

Here’s the source code for the file with this error.
This code calls a custom OAuth1 API to login a user when they try signing in, and then creates a user in Meteor’s DB with properties returned by that web service.

Thanks for any help you can offer!

Be well,

Call stack
