Example not working with Ember 2.13

[BryanHunt]

I'm trying to get your example line chart working and I'm using Ember 2.13. I think I figured out all of the dependencies, but now I'm getting this exception:

Error: let not found, and the catch-all block handler didn't handle it

Thanks for reporting this, @BryanHunt. I am pretty busy this week but I will be able to take a look over the weekend if not before.

@BryanHunt can you please share your sample app with me?

@BryanHunt have you installed ember-let?

Installing ember-let fixes the problem.

@chilicoder thank you for mentioning this. It sounds like it provides a fix! I'm sorry I haven't been active on this project lately, I'm glad that you were able to get this working. I will try updating the dependency structure so that the external library is not required.
