Scrapy project to Scrapinghub fails

Question

My scrapy projects works fine on my local machine. But, I'm getting an error when deploying to Scrapinghub:

$ shub deploy

I've some helper functions packed into the file myCrawlerHelper.py and am importing those into my spiders and items.py. I believe the problem is associated with this.

I use splash as well. I also noticed that the error messages include python 2.7, although I use 3.6

How can I get rid of this issue?
