Got "You need to set the owner in App-only context" while creating Modern Team No Group site collection using OfficeDevPnP package

Question

I am using OfficeDevPnP package to create new Modern Team No Group site collection but i got below error

"You need to set the owner in App-only context". See the function execution logs for additional details. ---> System.Exception: You need to set the owner in App-only context at OfficeDevPnP.Core.Sites.SiteCollection.d__8.MoveNext()

Here is my code,

using (ClientContext context = authManager.GetAppOnlyAuthenticatedContext("TenanatUrl", "ClientId", "ClientSecrete"))
{
    var creationInformation = new OfficeDevPnP.Core.Sites.TeamNoGroupSiteCollectionCreationInformation(siteUrl, siteName, userName);
    var results = await context.CreateSiteAsync(creationInformation);
}

I am using AppOnly Context here and also provided tenant full control permissions.

Answer 1

The permissions are correct, but in App-only context you need to pass the owner name.

This method, TeamNoGroupSiteCollectionCreationInformation(siteUrl, siteName, userName) accepts 3 params the last of which is description. But you need to pass the owner value which is necessary in apponly context, so modify the code as below:

var creationInformation = new TeamNoGroupSiteCollectionCreationInformation
{
    Url = siteUrl,
    Title = siteName,
    Owner = userName // login name of a user
};

var results = await context.CreateSiteAsync(creationInformation);
