I am trying to achieve creation of a scratch org in the 30 days trail version of Dev hub account as shown below from Dream force 2017 Developer Keynote.
I got the below error!
Have anyone tried to configure the scratch org with sourceorg?
The feature being discussed in the video is not generally available for all. It is related to Org Shape for Scratch Org. It is currently in Pilot and only available for people taking part in the pilot program. So you won't be able to use it until it is GA.
