  messages: string[]
): ServiceFault {
    const response = new ServiceFault();
    response.responseHeader.serviceResult = statusCode;
    // xx response.serviceDiagnostics.push( new DiagnosticInfo({ additionalInfo: messages.join("\n")}));

    assert(_.isArray(messages));
    assert(typeof messages[0] === "string");

    response.responseHeader.stringTable = messages;
    // tslint:disable:no-console
    console.log(chalk.cyan(" messages "), messages.join("\n"));
    return response;
