Hi @Modus Dev

Please check the value of templateType and OMDALConstants.Ask. Per my test, I can successfully create a subsite by following code

WebCreationInformation oWebCreationInformation = new WebCreationInformation();
// This is relative URL of the url provided in context
oWebCreationInformation.Url = "NewSubSite";
oWebCreationInformation.Title = "NewSubSite Site";
oWebCreationInformation.Description = "NewSubSite description";
 
// This will inherit permission from parent site
oWebCreationInformation.UseSamePermissionsAsParentSite = true;
 
// "STS#0" is the code for 'Team Site' template
oWebCreationInformation.WebTemplate = "STS#0";
oWebCreationInformation.Language = 1033;
 
Web oWeb = clientContext.Site.RootWeb.Webs.Add(oWebCreationInformation);
clientContext.ExecuteQuery();
