Desktop (please complete the following information):
Renku version: 0.6.1.dev3
OS: Linux (#1 SMP Debian 4.19.67-2+deb10u1 (2019-09-20))
Python: 3.7.3

Additional context
The import was tested before and after creating the dataset locally on renku. Both times the bug report was the same and occurred at the same point.

Could you try to upgrade your renku version? We had a regression that caused this bug but it should be fixed.

[jen-thomas]

I've updated and don't get this error anymore. Thanks very much for your help!
