Hello everyone

I'm trying to create content programmatically. I had already done this in previous versions (9 & 10), now I use Umbraco 12.2.0. Now when I call ContentService.CreateAndSave() I get an error that the content cannot be saved with an empty name. However, I pass the following string “roland-schenk” to the method. Are there any new restrictions on the names of a node?

public void CreatePage(IMember member, TeacherProfile profile)
{
    var itemName =  $"{member.Name}".Replace(" ", "-");

    IPublishedContent? parent = null;

    if (ContextAccessor.TryGetUmbracoContext(out var ctx))
    {
        parent = ctx.Content.GetAtRoot().FirstOrDefault(c => c.ContentType.Alias == Constants.DocumentTypes.MsHomePage.Alias)?
            .Children.FirstOrDefault(c => c.ContentType.Alias == Constants.DocumentTypes.MsSchoolOverview.Alias);
    }



    if (parent != null)
    {
        var content = _contentService.CreateAndSave(itemName.ToLowerInvariant(), parent.Id, Constants.DocumentTypes.MsMusicTeacherPage.Alias);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Name, member.Name);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.InstrumentLocations, JsonConvert.SerializeObject(GetInstrumentLocationBlockList(profile.InstrumentLocations)));
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Website, JsonConvert.SerializeObject(new Link()
        {
            Url = profile.Website,
            Type = LinkType.External
        }));
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.TeachingType, profile.Subtitle);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Email, member.Email);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Lon, profile.Lon.ToString());
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Lat, profile.Lat.ToString());
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Address, profile.Address);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.City, profile.City);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.ZipCode, profile.ZipCode);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.State, profile.State);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Style, profile.Style);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.LessonsForAge, profile.LessonsFrom);
        content.SetValue(Constants.DocumentTypes.MsMusicTeacherPage.Fields.Member, JsonConvert.SerializeObject(member));
        _contentService.SaveAndPublish(content);
    } 
}
