Was this script sent to you by email or did you receive a link? Can you post the link?

It would take a few minutes to convert it to use tokens, but if it came directly from Jamf Support then they need to address this, and I can reach out to them.

Have you considered using Prune?

https://marketplace.jamf.com/details/prune

Awhile back I was given these directions from jamf - but since then have used Prune successfully

We can try using the API to do this. First we will want to find the range of class IDs. If you would like to get rid of all of them, then you can start with 1 for the lower range.

Navigate to Devices > Classes

Try to narrow down on the minimum and maximum class ID values by viewing them in the URL bar. I would suggest creating a new class to find the max value. Finding the minimum value can be difficult, however do your best to get as close as possible as this will save time when running the API query in the next steps. I may create a script to (Note: Scale this deletion, do not try to delete hundreds of classes on your first attempt, instead start with ten)

Open Terminal, and run the following API command to delete this range of classes. Make sure to replace the following values INSERT_JAMF_URL, the ID range 1-100, and INSERT_USERNAME.

curl -ksu INSERT_USERNAME -H "content-type: text/xml" INSERT_JAMF_URL/JSSResource/classes/id/[1-100] -X DELETE

the cURL way no longer works. Prune did not work for me as it would give me a server error after scanning the 676 class. I used the solution in this thread that provided a powershell script et el to delete the classes: Script to delete all classes imported by ASM in Jamf Pro
