Upload file to Sharepoint 2013 using web service - Object reference not set to an instance of an object

I'm trying to upload file to Sharepoint 2013 using web service copy.asmx

I've created simple project with the following method:

public bool UploadFile(string file, string destination)
{
bool success = false;
CopySoapClient client = new CopySoapClient();

if (client.ClientCredentials != null)
{
client.ClientCredentials.Windows.ClientCredential = new NetworkCredential("admin", "password", "domain");
}

try
{
client.Open();

string filename = Path.GetFileName(file);
string destinationUrl = destination +@"/"+ filename;
string[] destinationUrls = { destination };

FieldInformation i1 = new FieldInformation { DisplayName = "Title", InternalName = "Title", Type = FieldType.Text, Value = filename};
FieldInformation[] info = { i1 };
CopyResult[] result;
byte[] data = File.ReadAllBytes(file);

uint ret = client.CopyIntoItems(file, destinationUrls, info, data, out result);

if (result != null && result.Length > 0 && result[0].ErrorCode == 0)
success = true;
}
finally
{
if (client.State == System.ServiceModel.CommunicationState.Faulted)
client.Abort();

if (client.State != System.ServiceModel.CommunicationState.Closed)
client.Close();
}

return success;
}

CopySoapClient is part Copy service reference 

http://SPSITE/_vti_bin/copy.asmx

The method is called using following parameters:

UploadFile(@"C:\temp\test.txt", "http://SPSITE/sites/Connector/documents/test.txt");

The problem is, when program executes 

uint ret = client.CopyIntoItems(file, destinationUrls, info, data, out result);

the web service returns in result "Unknown error" with description "Object reference not set to an instance of an object."

I really don't know what I'm missing. Can anyone help me out?

Thank you.

P.S. I've noticed in examples provided on the Internet that people are using a Copy class from copy.asmx. But I only have CopySoapClient class.

missing the OPTIONAL element of <Fields> and <FieldInformation >, resulted ErrorCode="Unknown" ErrorMessage="Object reference not set to an instance of an object." . even though, Field and FieldInformation supposed to be optional. It could be the server side configuration. Anyway, it works for me now, adding all attributed, required/optional.

you used the right web services but on wrong SharePoint site. Try to make this web services reference on the same sharepoint site you have posted here as target library.
