Hello, 

I am just looking at building simple File integration to print some pallet labels,  I started by creating a blank label and connecting it to the sample XML than displaying only the printer name, eventually I would be displaying a barcode with serial number. 

Sample XML

<XMLScript Version="2.0" Trusted="true">
  <Command Name="Print Document">
    <Print SaveAfterPrintCondition="IfModified" ActionInitiated="true" ReturnPrintData="false" ReturnSummary="false" ReturnLabelData="false" ReturnChecksum="false" ReturnDataSources="false">
      <Format CloseAtEndOfJob="false" SaveAtEndOfJob="true" RegenerateThumbnail="false">lib://TraceLink/Pallet_RX.btw</Format>
      <PrintSetup>
        <UseDatabase>true</UseDatabase>
        <Printer>ITEAOPrinter</Printer>
      </PrintSetup>
      <RecordSet Type="btXML" AddIfNone="true">
        <XMLData><![CDATA[<Variables><Variable Name="SSCC_SERIAL_NUMBER">00000700300000074135</Variable></Variables>]]></XMLData>
      </RecordSet>
    </Print>
  </Command>
</XMLScript>

In Bartender I used the database set up connection to print and test printed with no issues. 

When I build the File integration I followed the knowledge base and was able to get it working using the sample files from Bartender, but now that I have my own XML and recreated all the steps I get the attached error show in the screenshot.  Any help would be appreciated.
