Newbie question - open /var/lib/cattle/envfiles/smtp.txt: no such file or directory

I cloned the following repository - https://github.com/kobotoolbox/kobo-docker.git
I am trying to deploy this application via my local install of rancher, but getting the following error - Error (open /var/lib/cattle/envfiles/smtp.txt: no such file or directory)

This is after trying to deploy my kobotoolbox stack having uploaded the following docker-compose file:
