Django operational error: "Field 'partner_id' doesn't have a default value\" [Hawthorn.master release]

Dear all,

Since I’d like to upgrade my edX ginkgo system to ironwood, I have to get ginkgo (for test purposes), hawthorn and ironwood running.
I have a different thread referring to the attempts on ginkgo, this one is about an error I get when trying to install Hawthorn.master or Hawthorn.2 - exactly the same problem.

System information: Ubuntu 16.04 LTS, 8Gb RAM, 4 CPU Cores
Trying to install Hawthorn.master or Hawthorn.2 for edX Update from Ginkgo to Ironwood.

I follow the native installation instructions. In Task [edx_django_service : run post-migrate commands] the following error appears.

Thank you very much in advance.

Best regards
