@lauraluiz is this issue relevant to this repository or does this belong to the http://demo.commercetools.com setup?

[lauraluiz]

It was relevant to this repository, as this is the one that contains the data used in iron.io to import sunrise data. demo.commercetools.com doesn't have any particular setup related with iron.io.

On our side we no longer need to upload this script to iron.io. If on your side you don't need this either, we can close the issue.
