Unable to add user to SharePoint Site security group when site name has special characters

[mohammadamer]

Expected behavior

The expected behavior here is to execute Add-PnPGroupMember and get the member added to the SPO group but instead got error and when tried with a site which has no special characters it worked fine.

Actual behavior

Error: Add-PnPGroupMember : Invalid request.

Steps to reproduce behavior

A SharePoint Site that has a name with special characters EX: Økonomi

$site = "https://tenant.sharepoint.com/sites/Økonomi"
$client1 = "00000000-0000-0000-00000000"
$cert1 = "C:/Cert1.pfx"
$certPass1 = (ConvertTo-SecureString -String "Password1" -AsPlainText -Force)
Connect-PnPOnline  -Url $site -ClientId $client1 -CertificatePath $cert1 -CertificatePassword $certPass1 -Tenant "tenant.onmicrosoft.com"

$MembersGroup = Get-PnPGroup -AssociatedMemberGroup
Add-PnPGroupMember -LoginName "AD Group Title" -Identity $MembersGroup.Title

Error:
Add-PnPGroupMember : Invalid request.

Add-PnPGroupMember -LoginName "AD Group Title" -Identity  $MembersGroup.Id
Same error:
Add-PnPGroupMember : Invalid request.

What is the version of the Cmdlet module you are running?

1.7.0

Which operating system/environment are you running PnP PowerShell on?

• [x] Windows

Diving into this.

@mohammadamer How did you even manage to create a sitecollection with Økonomi in the URL? If I try it through the web UI it will just take out that entire letter. If I try it using New-PnPSite it will normalize it to Okonomi instead.

[mohammadamer]

@KoenZomers I am using PnP Powershell and the site has been created with this title "ØkonomiOgFinansiering" and this name "ØkonomiOgFinansiering" :) Even different sites with special characters have been created using PnP Powershell without getting the normalizing of names but when it came to different power shell commands like Add-PnPGroupMember I found out the issue as I described.

[KoenZomers]

I need more information to try to reproduce this. When I simply use New-PnPSite to try to create a site with this name, it normalizes it to a normal o:

How exactly did you create a site where the Ø would be retained in the URL?

[mohammadamer]

@KoenZomers This is how we create site using PnP Powershell. The only difference is that I am using a JSON file which contains every site Title, URL etc. Urls in my Json file has URL and title with these special characters as I explained.

I a for loop I am using the following line to create sites using the data in JSON file. New-PnPSite -Type $Site.SiteType -Title $Site.Title -Url $Site.URL -Owner $Site.SiteOwner

[KoenZomers]

Which version of PnP PowerShell are you using? New-PnPSite does not have a -Url parameter. New-PnPTenantSite does, but that does not have a Type parameter. So I'm still confused :)

Can you share the output of:

Get-InstalledModule *PnP* | Select Name, Version | FT

[mohammadamer]

@KoenZomers, After you specify the type parameter, Url parameter will be present.

PnPPowershell Version PnP.PowerShell 1.7.0

@mohammadamer - I think its a bug in SharePoint's side that you were able to create a site with a URL having special characters. As Koen mentioned, its not possible to create a site from UI with this URL. We added a fix in the site creation code to normalize these characters.

Can you try with the latest nightly to create a new site and then add members ? In any case, we are not going to be able to fix the issue because it is the server that is sending us this response.

@gautamdsheth

Well, I knew now that even SharePoint is not supporting it but I had tried before with PnPPowerShell and it worked that's why I thought it's supported. Now, I am trying with PnPPowerShell 1.8.0 and the site created without any normalization which means that bug still present.

[gautamdsheth]

Can you provide the minimal repro steps that you used for site creation ? Am not able to create sites with special chars, so I could be missing something.

We are using the latest PnP version , so maybe you can try with that ?

[mohammadamer]

@gautamdsheth

Power shell for site creation:

Sites have been created:

[KoenZomers]

I can create a site with that character in the URL now using:

new-pnpsite -type TeamSite -title "ØkonomiOgFinansiering1" -Url https://tenant.sharepoint.com/sites/ØkonomiOgFinansiering1 -owner [email protected]

When I then connect to that tenant and try to add a user to the group, it works without any problems:

Still must be missing something here, but no idea what.
