Crystal report Error: The types of the parameter field and parameter field current values are not compatible

Hello,

this is my code in C# for printing a Crystal Report.

protected void Print(object sender, EventArgs e)    
       {    
           ImageButton lnkRowSelection = (ImageButton)sender;    
           ReportDocument cryRpt = new ReportDocument();    
    
           string[] commandArgs = lnkRowSelection.CommandArgument.ToString().Split(new char[] { ',' });    
           string idno = commandArgs[0];    
           string company = commandArgs[1];    
    
           try    
           {    
               if (lnkRowSelection.CommandArgument.ToString() == null)    
                   Response.Redirect("Default.aspx");    
               else    
               {    
                   if (company == "True")    
                       cryRpt.Load(Server.MapPath("~/Reports/rep1.rpt"));    
                   else    
                       cryRpt.Load(Server.MapPath("~/Reports/rep2.rpt"));    
    
                   if (lnkRowSelection.CommandArgument.ToString() != null)    
                   {    
                       cryRpt.SetParameterValue("@idno", idno);    
                       cryRpt.SetParameterValue("Office", agr.getOffice());    
                       cryRpt.PrintToPrinter(2, true, 1, 2);     
                   }    
               }    
           }

Rep1 and Rep2 were created using Report Wizard and are binded to a sproc. Idno is a parameter for the sproc and office is a second parameter i added to the report. I use integrated connection (even though I tried SQL authentication and I still get the same errors)

The problem is that I get the error "The types of the parameter field and parameter field current values are not compatible" but only when I use the published version. If I run the application through Visual Studio the report is printing just fine. I'm using Windows Server 2012 R2, IIS 8.5 , Crystal Reports 13, .NET Framework 4.5.2 So far I've tried the following:

Checked that both parameters are data type String and getting string as input.  Checked that there are no null values as input. Change .rpt properties to Content Added asp_client to my application folder. Tried printing a report without parameters, even though I don't get the error the report didn't print either.

Any ideas what might be wrong? Thank you in advance.
