hello i have a problem when i call my stored procedure from c# , In my oracle stored procedure that i'm calling i have 2 inputs and two outputs , my inputs the first input is CLOB means it will passs string in c# code and the second input is number.my outputs first out is a defined object in my stored procedure
t_t_out_house_details and this object returns 10 values, the second output is number.
my stored procedure:

PROCEDURE prc_get_impacted_houses(p_polygon_geom      IN CLOB,
                                    p_imkl_id        IN NUMBER,
                                    p_out_house_details OUT t_t_out_house_details,
                                    p_return_cd         OUT NUMBER);

im calling this stored procedure and passing these two inputs using c# like that:

static public void CallingStoredProcedure(string PolygonGeom, int PImklId)
        {


            //my custom object 

            try
            {

                //conection to the database

                using (OracleConnection conn = new OracleConnection("Data Source=; User ID=; Password="))
                {
                    
                    t_out_house_details houseDetails = new t_out_house_details();
                    OracleCommand cmd = new OracleCommand();
                    conn.Open();
                    cmd = new OracleCommand("prc_get_impacted_houses", conn);
                     cmd.CommandType = CommandType.StoredProcedure;

                    //first input
                    cmd.Parameters.Add("p_polygon_geom", OracleDbType.Clob).Value = PolygonGeom;

                    cmd.Parameters.Add("p_imkl_id", OracleDbType.Int32).Value = PImklId;

                    //Oracle Parameters

                    //first output
                    OracleParameter objParam = new OracleParameter();

                    objParam.OracleDbType = OracleDbType.Object;

                    objParam.UdtTypeName = "t_t_out_house_details";
                    objParam.Value = houseDetails;
                    //T_T_OUT_HOUSE_DETAILS
                    
                    objParam.Direction = ParameterDirection.Output;
                    cmd.Parameters.Add(objParam);

                    //second output
                    OracleParameter op = null;
                     op = new OracleParameter("p_return_cd", OracleDbType.Int32);
                    op.Direction = ParameterDirection.Output;
                    cmd.Parameters.Add(op);
                   // cmd.BindByName = false;
                    //Taking instance from my object 
                    
                    //execute my command
                    cmd.ExecuteNonQuery();
                    houseDetails = (t_out_house_details)objParam.Value;
                }


                ////Console.WriteLine(cmd.Parameters["p_return_cd"].Value);
            }
                catch(OracleException ex)
            {
                Console.WriteLine(ex.Message);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                //throw new Exception("Error " + ex.Message);
            }

also i have a c# object where i want to store my returning values from this stored procedure object to it.
my c# object

public class t_out_house_details
    {

            public string NET_CD { get; set; }
            public int SUBNET_NR { get; set; }
            public int CABLE_NUMBER { get; set; }
            public int MK { get; set; }
            public int KG { get; set; }
            public int KS { get; set; }
            public string HOUSENR_FIRST { get; set; }
            public string HOUSENR_FIRST_SUFFIX { get; set; }
            public string GEOMETRY { get; set; }
            public string PROJ_LINE_GEOM { get; set; }



    }

my problem that my code cant read the object type im defining using UTD user defind types.
my ode stuck here :

OracleParameter objParam = new OracleParameter();

                    objParam.OracleDbType = OracleDbType.Object;

                    objParam.UdtTypeName = "t_t_out_house_details";
                    objParam.Value = houseDetails;
                    //T_T_OUT_HOUSE_DETAILS
                    
                    objParam.Direction = ParameterDirection.Output;
                    cmd.Parameters.Add(objParam);

and give me this error: that he cant find my object :

OCI-22303: type ""."my stored procedure object type" not found
i want to know wht is the problem
im pasing a string and int and i tested this stored procedure on pl sql its working fine no errors.
