rasa: Getting errors when connecting to Git with rasa-x 0.26

Rasa version: 1.8

Rasa SDK version (if used & relevant): 1.8

Rasa X version (if used & relevant): 0.26

Python version: 3.6

Operating system (windows, osx, …): ubuntu

Issue: I updated rasa-x to 0.26, I followed the guide for connecting it to GitHub using the UI, I display all my data on my Rasa X UI, but I can’t train a model. When I try it I get the following error:
