Uncaught Error: Assertion Failed: The `element` helper polyfill encountered an unexpected error

I followed the suggestions on this thread - #84 - and pinned the resolution of the version of ember-element-helper to 0.6.1 in the package.json. That fixed my problems; apparently different addons were using different versions, which caused the problems above.

I get the same error with ember-cli-meta-tags v7.0.0

Upgrading ember-element-helper to 0.6.1 fixed the problem with ember-cli-meta-tags, but I'm getting the same problem with one of our internal uses of the element helper now, so I'll investigate that further.

I also tried to pinned the version of ember-element-helper (ember install ember-element-helper@^0.6.1) in my package.json, but it didn't work for me... :-(

@brianjgeiger can you share your package.json file with me?

Sure, you can find the diff with my changes at https://github.com/CenterForOpenScience/ember-osf-web/pull/1660/files#diff-7ae45ad102eab3b6d7e7896acd08c427a9b25b346470d7bc6507b6481575d519 - the resolutions section is key.
