Unable to get boolean value from oracle stored procedure

I am trying from hours to find out how I can get the returned value as boolean from oracle stored procedure.

I created a simple SP which is returning a boolean as out but when I pass the parameter as OracleDbType.Boolean I am getting error.

This is my sp

create or replace procedure nbq_out_test (pi_bool_in IN BOOLEAN,
                                  pi_var_in  IN VARCHAR2,
                                  pi_num_in  IN NUMBER,
                                  po_bool_out OUT BOOLEAN,
                                  po_var_out  OUT VARCHAR2,
                                  po_num_out OUT NUMBER) AS
BEGIN
    po_bool_out := pi_bool_in ;
    po_var_out := pi_var_in;
    po_num_out := pi_num_in;

END   nbq_out_test;

And this is my c# code

OracleCommand command = new OracleCommand("NBQ_OUT_TEST", con);
            OracleParameter param;
            command.BindByName = false;
            command.CommandType = CommandType.StoredProcedure;

param = new OracleParameter("PI_BOOL_IN", OracleDbType.Boolean, ParameterDirection.Input); //Works fine as input
            param.Value = true;
            command.Parameters.Add(param);

param = new OracleParameter("PO_BOOL_OUT",OracleDbType.Boolean,ParameterDirection.Output); //This is the line causing error.

            command.Parameters.Add(param);
command.ExecuteNonQuery();

This is the error

ORA-06502: PL/SQL: numeric or value error\nORA-06512: at line 1

I cannot modify the Stored Procedure to return 1 or 0 or anything similar.

The oracle version is 12.1.0.2.0

The Oracle.ManagedDataAccess.18.3.0

I have searched lot but most of the suggestion was to modify the SP which is not at my end.

Any suggestion will be great help.

OracleDbType doesn't seem to support Boolean.

I think your question already has an answer in below page. Boolean in OracleDbType
