According to Diana Barsan:
API auth component was refactored to use Promises, while the Export component still expects it to use callbacks.

As with all of these export issues that get raised, I'm not convinced anyone uses this export and we should drop it instead of fixing it. One less thing to maintain :-)

I was asked today about export of forms with images... so there may be users that use some of it. Do we have any activity tracking/logging to see which endpoints do get used?

[dianabarsan]

Calling Auth with a callback instead of a promise has been fixed. Unfortunately there is another bug caused by compression - where when using res.write method, calling flush method is required to actually send data.

LGTM.
