Symptoms
When you use the SharePoint Hybrid Picker, you receive the following error message during the Hybrid solution configuring phase:
Value cannot be null. Parameter name: My site URL or team site URL from Discovery Service is null or empty.
Cause
The issue occurs when users don't have permissions to create sites and the administrator doesn't have a OneDrive for Business site provisioned for their account.
Resolution
To resolve this error, grant permissions to the Everyone except external users group so that users can create personal sites in Microsoft 365, and then browse to the OneDrive for Business page as the administrator. Follow these steps:
Sign in to your tenant as a SharePoint administrator, and browse to the SharePoint admin center.
Select User profiles, and then select Manage User Permissions.
Add the Everyone except external users group to the Permissions dialog box if it isn't listed.
Verify that the Create Personal Site (required for personal storage, newsfeed, and followed content) permission is selected for the Everyone except external users group, and then select OK.
Browse to https://your_domain-my.sharepoint.com to provision the OneDrive for Business account for the administrator account.
NOTE Replace "your_domain" with the domain that you use for your organization.
Run the Hybrid Picker again.
