I virtually attended Wolfram's 2020 Conference back in October. I attended Wolfram Notebook Training session hosted by Abrita Chakravarty. Of course, off-line, I walked through her examples and tried them out with great satisfaction. Over time, I've gone back to my copy of her code, and added code to help me understand things more in depth.
Recently, after upgrading to Mathematica 12.2, from 12.0/12.1/12.1.1, I went back to this code and found code that had been working no longer functions. Besides upgrading to Mathematica 12.2, I had previously upgraded MacOS to Big Sur, and also purchased and installed SystemModeler 12.
Today, I created a new NB with just the first and simplest code from the training that had been failing, and ran it again. I've attached that below. It failed again. I then deleted Mathematica and its library from my iMac, the reinstalled from the Wolfram site, and tried the two statement code again. Again it failed on my machine.
The code is simply these two statements:
data3 = EntityClass["Country", "SouthAmerica"][
{
EntityProperty["Country",
"GDP", {"CurrencyUnit" -> "CurrentUSDollar",
"PerCapita" -> "PerCapita"}],
"LifeExpectancy",
"Population"
},
"EntityAssociation"]
followed by
BubbleChart[data3]
The two above statement were entered by me in one instance, and copied and pasted from the training slide show in another. Both resulted in the same failure. The data3 variable was set correctly in both cases, but the BubbleChart[data3] failed internally during a Rescale operation saying the "The argument .... at position 3 is expected to be a list of a lower bound and an upper bound." This error message is repeated, then other failure messages appear and the process runs until manually aborted.
