PowerShell script to capture version of Document Sets using CSOM in SharePoint Online. This script also lists out all the Document Set content type items along with the version information from a document library using the latest CSOM library released recently (version: 16.1.20317.12000 or above). Before this release, the only way to version a D…

Here is a sample output from this script

This doesn't work for me, the script run fine but returned doc set content 0 - looks like the contentype is not found after I put my contenttype name

Did you edit line 27, to replace "document set" with your own content type name? If so, undo that change and try again please.

Thanks for your quick reply. I have not changed the "document set" nor the 'Computed' in line 27. Here is the output
Document Library: TestingDocSetVersion
Total Item Count: 4
Found ( 0 ) DocumentSet content type items.

Are you sure there are Document Sets created in that library? Create few document sets and then try to run it again. I am sure you are of these steps:
Document sets must be first activated using Site Collection features, then you enable Adv. Settings for Library, and then add Doc Set content type to the library. Only then you can create Document Sets.

Yes I have activated Document Set feature on the site collection and created document set content type and I have created two document set items and uploaded attachments in their - actually the total count shows 4 items as you can see from the PS out put above. I am a SharePoint developer and I done all the document set settings rights as I have a couple of other similar libraries based on Doc set content type. I see you have a variable $CreateNewVersion = $true but not used or called anywhere in the script? or what's the PS module version that is required for this script if that's the issue?

Ensure you have latest SPO CSOM dlls.
Here is my PS version:
