I am using the SharePoint 2016 C# CSOM SDK to create a subsite in a site collection (code below). However, I get this error:
at Microsoft.SharePoint.Client.ClientRequest.ProcessResponseStream(Stream responseStream) at Microsoft.SharePoint.Client.ClientRequest.ProcessResponse()
The code does work and the site gets created, but I don't know what the error is?
Code:
ClientContext context = new ClientContext(sp2016url);
WebCreationInformation creation = new WebCreationInformation();
creation.WebTemplate = "{9D2F0ED0-8EAC-4E22-83D5-B44E5F2AED85}#legnewtemplate";
creation.Url = GetIDFromKey(legdata.file_reference);
creation.Title = "Site";
creation.Language = 1033;
creation.UseSamePermissionsAsParentSite = true;
Web newWeb = context.Web.Webs.Add(creation);
NetworkCredential cred = new NetworkCredential(@"xxxxx", "xxxxx", "xxxx");
CredentialCache cache = new CredentialCache();
cache.Add(new Uri(sp2016url), "NTLM", cred);
context.Credentials = cache;
// Retrieve the new web information.
context.Load(newWeb, w => w.Title);
context.ExecuteQuery();
