ibmcloud functions, (openwhisk) .cant connect to redis using net core 3.1 Could not load file or assembly 'System.IO.Pipelines

I'm trying to connect to IBM databases for redis instance from ibmcloud functions for days but i had no luck. I tried using ibmcloud supported version .netcore 2.2 and docker image core 3.1.

I can connect to redis without anyerrors from a local console app using code below.

I need your help. Thank you.

    public IbmRedisClient(JObject args)
    {
        X509Store store = new X509Store(StoreName.Root);
        var base64 = (string)args.GetValue("redis_connection_certbase64");
        string connURL = (string)args.GetValue("redis_connection_string");
        connURL = connURL.Replace("$PASSWORD", PASSWORD);
        Console.WriteLine("base: " + base64);
        X509Certificate2 ca  = new X509Certificate2(Convert.FromBase64String(base64));
        var EndPointCollection = new EndPointCollection();
        var options = new ConfigurationOptions
        {
            AbortOnConnectFail = false,
            Ssl = true,
            ConnectRetry = 3,
            ConnectTimeout = 5000,
            SyncTimeout = 5000,
            DefaultDatabase = 0,
            Password = "testadminpassword"
        };
        options.EndPoints.Add(host, 32326);
        options.EndPoints.Add(host, 0);

        options.CertificateSelection += delegate
        {
            return ca;
        };
        try
        {
             ConnectionMultiplexer muxer = ConnectionMultiplexer.Connect(options);

             conn = muxer.GetDatabase();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Root certificate import failed: " + ex.Message+" "+ex.ToString());
        }
        finally
        {
            store.Close();
        }

    }

Please try adding <_FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput> to your project file, haven't tried yet, but going by solution posted here for a similar problem.
