ember-cli-cordova Duplicate data property in object literal not allowed

I'm using Ember-cli with Ember-cli-cordova. I can launch my app fine in the browser with the ember server command. I can even install the app on my Samsung Note 4 where it works just fine.

However, when I try to install it on a Samsung Galaxy Tab 8, I get this error:

Uncaught SyntaxError: Duplicate data property in object literal not allowed in strict mode myapp-9439236f29026a083d4095515953a67d.js:1

It seems to be erroring out right at the define statement.

Any ideas why this would happen on one device but not another?
