Why is Add-SPOUser parameter Group null?

Question

I am working on adding templates in Microsoft 365 via Sharepoint and running this via Windows Powershell. So far so good. Now I want to run the script to "set" the template folder and permissions so that it is shown in the office environment.

On the following script I get an error, group is NULL

Add-SPOUser -Site $SharePointSiteUrl -LoginName ('c:0-.f|rolemanager|spo-grid-all-users/{0}' -f $AzureAdTenantId) -Group $SpoGroupVisitor.LoginName;

What am I doing wrong? Or do I need to create another group of users somewhere?

Error message is this:

Add-SPOUser : Cannot bind argument to parameter 'Group' because it is null.

At line:1 char:122

• ... ll-users/{0}' -f $AzureAdTenantId) -Group $SpoGroupVisitor.LoginName;
  • CategoryInfo : InvalidData: (:) [Add-SPOUser], ParameterBindingValidationException
  • FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.Online.SharePoint.PowerShell.AddSPOUser

would like to hear.

Hi @Machiel Korf | Korf KB ，

The error message suggests that the value of the Group parameter is null, which means that it is not being set or passed correctly in the script.

It is possible that the variable $SpoGroupVisitor is not being set correctly or is null. You may need to check the value of this variable and ensure that it is being set to a valid SharePoint group before running the Add-SPOUser cmdlet.

Alternatively, you may need to create a new SharePoint group and add users to it before running the Add-SPOUser cmdlet.
