The "-Parallel" parameter is present in PowerShell 7. It's not present in PowerShell 5. Which version of PowerShell are you using?

Well, 5.238.11 doesn't look like a PowerShell version number.

You might get a better answer by adding an appropriate Azure tag to your original post, or by asking the question on the StackOverflow site.

The error you're getting implied the use of PowerShell 5.
