  We upgrage AR to 15.1.3 just lately. When we open the reports what include some parameters to preview them, It always show me the error message “The JSON value could not be converted to System.Collections.Generic.Dictionary`2[System.String,GrapeCity.ActiveReports.Web.Viewer.I.+ParameterValuesQuery+RequestFields]. Path: $.request | LineNumber: 0 | BytePositionInLine: 24.”
  
  What can we do?

  Hello,

  Can you please share the report with us so that I can replicate the issue at my end. Also, in which viewer are you previewing the report.

  Thanks,

  Hello,

  Can you please tell in which version that you had created this report. I try to open the report in AR10-AR15 version but give the error while opening the report.

  Thanks,

  Hello,

  It shows the error “: ‘Data at the root level is invalid. Line 1, position 1.’”. Could you please recheck at your end with same report.

  Thanks,

  Thanks for your feedback, I have found the root cause what come from the UTF-8 BOM format of report file. We make some step to get the contents.

  byte[] bomBuffer = new byte[] { 0xef, 0xbb, 0xbf };
          if (content[0] == bomBuffer[0]
                      && content[1] == bomBuffer[1]
                      && content[2] == bomBuffer[2])
          {
              var xmlStr = System.Text.Encoding.UTF8.GetString(content, 3, content.Length - 3);
              content = System.Text.Encoding.UTF8.GetBytes(xmlStr);
          }
