Trying to upload the SIC Descriptions CSV File provided in the module but after following the steps, the upload fails and gives the following error: 
Something went wrong while executing the digest node: Only the dataflow owner or users with the View All Data permission can download the log. (02K3h000000kN0AEAU_03C3h000000t4Y6EAI)
Any thoughts?

I am practicing on trailhead via using my developer org. The chalenging asked me to Create a Guest Administrator and deactivate it. I am currenly the System Administrator of my developer org. We have only one license for System Administrator. How should we solve this issue in order to:
Create a new user using the System Administrator profile and then deactivate that user to preserve the licenses in your org.The new user must use the System Administrator Profile.
The username for the new user must include 'guestadmin' somewhere in it.
The new user must be inactive.
I need some hints or advices. Thanks.
