Uncaught (in promise) TypeError: object is not a function #407

Closed mcmath closed 8 years ago

mcmath commented 8 years ago

I'm getting this unhelpful error message in Chrome after upgrading to es6-shim@0.34.3.

Uncaught (in promise) TypeError: object is not a function            index.html:1
    at Object.defer (native)
    at chain (native)
    at then (native)

I'm using this as part of an Angular 2 application, bundled with Webpack. When I downgrade to es6-shim@0.34.2 the error goes away. And I'm not getting any errors in Firefox.

@akim-mcmath I assume you're using Chrome Canary?

This is a trivial console warning that you can absolutely ignore and won't affect your program in any way. That said, it should have been resolved by v0.34.3 (and was present in v0.34.2). If you could somehow narrow it down to a line in es6-shim that would help a lot.

fwiw, I can't reproduce this in Chrome or Chrome Canary with v0.34.3.

@ljharb Thanks for your reply. I'm using Chrome 48.0.2564 on OSX actually. I also neglected to mention that the program seemed to be working fine otherwise. If it's trivial, then you don't need to worry about it for my sake. However, I seem to have found the source of the warning on line 2562 of v0.34.3.

I don't know why it's not reproducible. Could it be specific to OSX? In any case, I believe I've found a fix, which I can submit if you would like.
