Graph API Error for Italian Language SharePoint Sites

Question

There is an issue with the Graph API endpoint:

https://graph.microsoft.com/v1.0/groups/<groupId>/sites/root

This request works successfully for SharePoint sites created in English but returns the error "Unable to provision resource." for sites created in Italian.

The SharePoint site being created is a "teams site" using the "teams standard" template. The language selection is shown in the image below:

The same error occurs for the following endpoint:

https://graph.microsoft.com/v1.0/groups/<groupId>/drive/root

The output error is consistently:

{
    "error": {
        "code": "ResourceNotFound",
        "message": "Unable to provision resource.",
        "innerError": {
            "date": "2025-05-14T08:04:09",
            "request-id": "e90c0c07-0d55-4b1b-89a5-f5e6027588f6",
            "client-request-id": "0c8f2d1d-d045-d664-35af-8b6d8e6b6698"
        }
    }
}
