Hello! I've been working my way through An Elementary Introduction to the Wolfram Language using Programming Lab in Wolfram Open Cloud. In Chapter 45, I have run into a big challenge. The chapter and associated exercises use an example planets and moons data set. The instructions say to load the data with:

planets=CloudGet["http://wolfr.am/7FxLgPm5"]

However, whenever I try that (logged in or not), I see a message box: The Wolfram Engine has been terminated and this error message:

URLExpand: Unexpected client error:  {sig?{Not enough data to create a signature},uuid?{Invalid user uuid}} .

As a workaround, I've tried to recreate the dataset myself. But after spending hours trying to get the moon data (and finding a lot of masses missing in results), I'd like to be able to do and check the exercises with the example data and troubleshoot missing data another time.

Thanks in advance for your help!
