I am trying to call a SSRS report via SSIS using the solution found here:https://www.mssqltips.com/sqlservertip/3475/execute-a-sql-server-reporting-services-report-from-integration-services-package/

I the script runs without error but creates a blank (4kb) Excel file. The parameters match those found in the RDL, however, ServiceArea, Location are integer values in the SQL DB. Could my issue be the data types?

    End Enum
    Protected Sub SaveFile(ByVal url As String, ByVal localpath As String)
        Dim loRequest As System.Net.HttpWebRequest

        Dim loResponseStream As System.IO.Stream
        Dim loFileStream As New System.IO.FileStream(localpath, System.IO.FileMode.Create, System.IO.FileAccess.Write)
        Dim laBytes(256) As Byte
        Dim liCount As Integer = 1
        Try
            loRequest = CType(System.Net.WebRequest.Create(url), System.Net.HttpWebRequest)
            loRequest.Credentials = System.Net.CredentialCache.DefaultCredentials
            loRequest.Timeout = 600000
            loRequest.Method = "GET"
            loResponse = CType(loRequest.GetResponse, System.Net.HttpWebResponse)
            loResponseStream = loResponse.GetResponseStream
            Do While liCount > 0
                liCount = loResponseStream.Read(laBytes, 0, 256)
                loFileStream.Write(laBytes, 0, liCount)
            Loop
            loFileStream.Flush()
            loFileStream.Close()
        Catch ex As Exception
        End Try
    End Sub
    Public Sub Main()
        Dim url, destination As String
        destination = Dts.Variables("Folder_Destination").Value.ToString + "" + "Report_" + Dts.Variables("Location").Value.ToString + "_" + Format(Now, "yyyyMMdd") + ".xls"
        url = "https://websiteURLt&rs:Command=Render&Location=" + Dts.Variables("Location").Value.ToString + "&ServiceArea=" + Dts.Variables("ServiceArea").Value.ToString + "&StartDate=" + Dts.Variables("START_DATE").Value.ToString + "&EndDate=" + Dts.Variables("END_DATE").Value.ToString + "&DateType=" + Dts.Variables("DateType").Value.ToString + "&rs:Format=EXCEL"
        SaveFile(url, destination)
        Dts.TaskResult = ScriptResults.Success
    End Sub
End Class

The variables in the SSIS package are defined as STRING, Date/Time, and INT64 respectively.
