C# System.Net.HttpRequestException

I keep getting an error using the C# 18.4 version of the Client Library when attempting to create a Media Event. The media event code is below

static List<string> CreateMediaEvent(Entry entry, Client client)
        {            
            List<string> Ids = new List<string>();
            MediaEntry mediaEntry = new MediaEntry
            {
                MediaType = MediaType.VIDEO,
                Type = EntryType.MEDIA_CLIP,
                Name = entry.Title,
                Tags = entry.Tags,
                UserId = "RecordScheduleGroup",
                EntitledUsersEdit = entry.CoEditors,
                EntitledUsersPublish = entry.CoPublishers,
                CategoriesIds = entry.CategoryIds
            };
            bool done = false;
         
            
            OnCompletedHandler<MediaEntry> handler = new OnCompletedHandler<MediaEntry>(
                (MediaEntry result, Exception e) =>
                {
                    Ids.Add(result.Id);
                    Ids.Add(result.ReferenceId);
                    Ids.Add(result.RootEntryId);
                    Ids.Add(result.TemplateEntryId);                    
                    WriteLog("MediaEntry List for Create Media Entry result: " + ResponseToString(result));
                    done = true;
                });
            MediaService.Add(mediaEntry)
            .SetCompletion(handler)
            .Execute(client);
            while (!done)
            {
                Thread.Sleep(100);
            }

            return Ids;
        }

My client code is

        static Client createKalturaClient()
        {
            

            Configuration config = new Configuration();
            config.ServiceUrl = "https://www.kaltura.com/";
            Client client = new Client(config);
            

            SessionType type = SessionType.ADMIN;
            int expiry = 86400;
            string privileges = "";
            client.KS = client.GenerateSession(<client id>, <admin secret from https://developer.kaltura.com/>, <my publisher email with admin privs> type, expiry, privileges);
            return client;
        }

Error message is below

I am able to get a session with type ADMIN and a client.KS string, yet when I try to perform any action I get denied.

What does the error mean? That my session does not have privileges to do what I am requesting?

Is there an API call that can return information on the privileges of the session I am running?

Thank you
