SSRS/ASP.NET using ReportExecution2005 Reference. Setting all required report input parameters but still getting : One or more parameters required to run the report have not been specified.

Question

Although this has been asked before, none of the answers provided solve my issue. I AM passing in all of the required report parameters and all have HasValidValue set in the State property of the parameter array of ExecutionInfo. I am using ReportExecution2005.asmx in my ASP.NET web application. There is no GetParameters() call method to ReportExecution2005.ReportExecutionService object.

My report is calling a subreport so the input parameters are identical to the main report and the subreport. There are 4 single value inputs (two integer, two text) and then one Multivalue text input parameter which I supply multiple values for. I have double and tripled checked that the values I'm setting in the Multivalue input parameter match exactly one of the default parameters.

Here is the code that setups up the reports and renders/writes it out to a PDF file:

protected void btnPrintReq_Tests_Click(object sender, EventArgs e)  
        {  
            string query = string.Format("SELECT PatientFName, PatientLName, Address1 + ' ' + Address2 AS Address, City, Region AS State, PostalCode, Email, Phone, Gender, DOB, CONVERT(VARCHAR, ClinicID) AS ClinicID FROM Tbl_ShippingDropShip WHERE RequestID = {0}", giRequestID.ToString());  
            string sClinicID = string.Empty;  
  
            try  
            {  
                //get the drop ship test order details  
                SqlDataReader reader = default(SqlDataReader);  
  
                reader = o_cSQL.RunSQLReturnDataReader(query);  
  
                REService.ReportExecutionService rs_ext = new REService.ReportExecutionService();  
                rs_ext.Credentials = System.Net.CredentialCache.DefaultCredentials;  
                rs_ext.Url = ConfigurationManager.AppSettings["ReportExecutionServer"];  
  
                List<string> ordereditems = new List<string> { };  
  
                ordereditems = GetOrderedItems(); //panels and profiles  
                int numordereditems = ordereditems.Count;  
  
                List<String> comments = new List<String>();  
  
                if (cbIce.Checked)  
                    comments.Add("Ice");  
                if (cbKit.Checked)  
                    comments.Add("Kit");  
                if (cbSwabs.Checked)  
                    comments.Add("Swabs");  
                if (cbGoldTop.Checked)  
                    comments.Add("Gold Top");  
                if (cbNeedlePack.Checked)  
                    comments.Add("Needle Pack");  
                if (cbButterflyPack.Checked)  
                    comments.Add("Butterfly Pack");  
  
                if (comments.Count == 0)  
                    comments.Add("");

                    int j = 0;  
                    for (int  i = 4; i < rValues.Length;  i++)  
                    {  
                        rValues[i] = new REService.ParameterValue();  
                        rValues[i].Name = "PanelsNProfiles";  
                        rValues[i].Label = "Panels and Profiles :";  
                        rValues[i].Value = ordereditems[j++];  
                    }  
  
                }  
  
                REService.ExecutionInfo res_info = new REService.ExecutionInfo();  
  
                res_info = rs_ext.LoadReport("/zReportSandbox/RequisitionDS", historyID);  
  
                res_info = rs_ext.SetExecutionParameters(rValues, "en-us");

                Common.CommonUtilities.FatalError(sPageName, "btnPrintReq_Tests_Click", query, ex.Message.ToString(), ex.ToString());  
            }  
        }  

I have noticed that the ExecutionInfo item shows me all parameters in the array of the report, meaning the required INPUT parameters AND the INTERNAL parameters, but also noticed that for the INTERNAL parameters, the default value that was set in the report is satisfied and ExecutionInfo shows them with the State of HasValidValue.

The following list is what I know

1. the report works on its own, so the Main report that calls the Subreport has no issues creating the PDF
2. there report when run in SSRS does prompt for the 4 input parameters
3. I have tried the removal of the report in SSRS and redeployed it because there were many that suggested this somehow fixes issues like this.

It would be nice if the error would state what parameter it sees as not being satisfied, even if there are more than one, then simply listing the first one before erroring out would help a developer work through the issues.

The attached picture shows the values I'm passing in for the multivalue parameters (PanelsNProfiles). I'm also attaching my RDL files for the main report and the Subreport, but had to add a (.txt) file extension to them to be able to upload them.

Here is the error in the SSRS execution log:
