Are your SharePoint sites configured to use non-English document library names? There's a line in the script to set the value for the language your tenant uses:

$SharedDocFolder = "/Shared%20Documents" # These values are to allow internationalization of the SPO document library URL. For French, this would be "/Documents%20partages"

Thanks for your fast response.
I've changed with the following line with no luck:
$SharedDocFolder = "/Documenti%20condivisi" # It's in italian
Below an example of the URL
https://tenant.sharepoint.com/sites/ClientVenueOperations/Documenti%20condivisi/Forms/AllItems.aspx?RootFolder=%2Fsites%2FClientVenueOperations%2FDocumenti%20condivisi%2FGeneral%2FTTTT&FolderCTID=0x01200022E44C59819C56418ADCEF3A32FD9D1C

What's in the $SPOData variable? The problem, is coming when the script attempts to parse it in this command:

$SPOUrl = $SPOData.WebUrl.SubString(0,$SpoData.weburl.IndexOf($SharedDocFolder))

Maybe the WebUrl part of $SPOData is not present... But I can't debug your tenant.... You need to do that,. You could just comment the command out of the script to see if that gets past the issue. AFAIK, all that this does is figure out the URL for the site and document library.

Hmmm... I tested to see if the code could parse the $SPOData,.WebURL property. It works.

$WebUrl = "https://tenant.sharepoint.com/sites/Test/Documenti%20condivisi"
$SharedDocFolder = "/Documenti%20condivisi"
$X = $WebUrl.SubString(0,$weburl.IndexOf($SharedDocFolder))
$X
https://tenant.sharepoint.com/sites/Test

Something odd going on...

BTW, it looks like this is an empty document library. Has anyone ever accessed it?

stefanopagliuca · Answer 7 · Fri Aug 06 2021 05:17:51 GMT+0800 (China Standard Time)

Good question, I’ll try to investigate. I’ll let you know. Do you think that only this Teams or SharePoint site is causing the problem?

stefanopagliuca · Answer 8 · Fri Aug 06 2021 22:42:38 GMT+0800 (China Standard Time)

Hi, unfortunately the issue is related for each document library, I'm able to run script only if I put a comment in the script without any information about sharepoint

Tony Redmond · Answer 9 · Sat Aug 07 2021 21:02:01 GMT+0800 (China Standard Time)

I added some code to the script that I think will help with local language values for SPO document libraries. You can download the updated script and try it out.

Wonderful thanks, I'll try ASAP... Keep you updated. Regards.
