Loading from WPL example planet & moon data for An Elementary Intro Ch 45?

Posted 8 years ago

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!

However in Mathematica Online the execution works...

Moderators take note... and comment or report it as a bug in the Programming Lab

From the Programming Lab on-line I get the same error as the original poster... this is a bug I suspect

Hey Carl:

Since you were looking for a workaround, I tried that CloudGet[] from the desktop, it works:

moon data from desktop

Then I tried to get the InputForm[] so your could copy/paste the data, but the front end complains about the DataSet syntax. At least all of the data is there (in the attached Notebook).

It works perfectly fine for me...

Execute

URLExpand["http://wolfr.am/7FxLgPm5"]

it should yield

https://www.wolframcloud.com/objects/8faea9d5-66d4-44d7-8da3-b22d0e36031c

also make sure that both quotation marks in the URL are regular ones ... not curly quotes... just a thought...
