How to handle an exception?

Question

SQLite

Hello!
There is an application and a server, both written in C#. The form has a picturebox and a button, when clicked, an sql-query with SELECT is generated, this query is sent to the server, then the server pulls the picture from the database as a byte array, sends this byte array back to the application, and after the application receives this byte array , you need to display this array of bytes into a picture in the picturebox.
In this piece of code, a request is sent to the server to take a picture:

stream = Client.GetStream();
string Message3 = $"SELECT Image FROM users WHERE Login = '{LoginField.Text}'";
byte[] command3 = Encoding.UTF8.GetBytes(Message3);
stream.Write(command3, 0, command3.Length);

In this piece of code, the server takes the image after receiving the request and sends it back:

byte[] cmd = new byte[64];
                        StringBuilder builder = new StringBuilder();
                        int bytes = 0;
                        do
                        {
                            bytes = stream.Read(cmd, 0, cmd.Length);
                            builder.Append(Encoding.UTF8.GetString(cmd, 0, bytes));
                        }
                        while (stream.DataAvailable);

                        string message = builder.ToString();
                        Console.WriteLine(message);
                        stream.Flush();
                        if (message.Contains("SELECT"))
                        {
                         if (message.Contains("Image"))
                        {
                         SqliteConnection connect = new SqliteConnection("Data source = accounts.db");
                                connect.Open();
                                SqliteCommand command = new SqliteCommand(message, connect);
                                command.ExecuteNonQuery();
                                SqliteDataReader Reader = command.ExecuteReader();
                                while (Reader.Read())
                                {
                                    if ((string)Reader["Image"] == "")
                                    {
                                        string foto = null;
                                        byte[] image = Encoding.UTF8.GetBytes(foto);
                                        Console.WriteLine(image);
                                        stream.Write(image, 0, image.Length);
                                    }
                                    else
                                    {
                                        string foto = (string)Reader["Image"];
                                        byte[] image = Convert.FromBase64String(foto);
                                        Console.WriteLine(image);
                                        stream.Write(image, 0, image.Length);
                                    }
                                }
                         }

In this piece of code, the sent picture is received and displayed in the picturebox:

byte[] GetData3 = new byte[128];

            MemoryStream memoryStream = new MemoryStream(GetData3);
            pictureBox1.Image = Image.FromStream(memoryStream);

And in this line

pictureBox1.Image = Image.FromStream(memoryStream);

throws an exception:

System.Argument.Expection: Invalid parameter.

For what reason could such an exception appear and how to fix it?
