1.5 fails build with "Error: StringMap expected string key"

[Blackbaud-KevinHutson]

@lawrencec Hey, I think there may be an issue with 1.5.
Note that 1.4 seems to be working fine so it's not an emergency for us as I just pinned the version to 1.4.0.

This morning we kicked off a Jenkins build which runs our app that uses Unroll.
package.json was set to ^1.1.0 so our build installed 1.5 and got the following.

abbreviated Jenkins console output:

unroll@1.5.0 node_modules/unroll

...later...
[661] ./~/unroll/index.js 42 bytes {0} [built] [1 error]
... and finally ...

ERROR in ./~/unroll/lib/unroll.js
Module build failed: Error: StringMap expected string key

Let me know if I can provide more information that might be helpful to reproduce this issue.
I might be able to lend some of my time to pinpoint the cause.

This is for an AngularJS (1.x) app using Gulp, Karma and Jasmine.

[lawrencec]

Hmmm, I'm having trouble replicating this. I suspect a transformation issue of some kind. Are you using babel?

[Blackbaud-KevinHutson]

Yep, we are using babel. Here is a dump our package.json if that's helpful.

This apps is a little dated now. All of our new repo's are using the latest Angular now.

[Blackbaud-KevinHutson]

No rush on this. It isn't blocking us. We are pegged at 1.4 for now. If some time opens up we can test out 1.5, we can try it. I just wanted to let you know the error did exist for us at 1.5.

[mreinstein]

I'm also pegged @ 1.4.0, because 1.5.0 broke usage with all node versions < v6. unroll@1.5.0 really should have been unroll@2.0.0.
