SpreadsheetAddRows Limitation (ArrayIndexOutOfBoundsException)

java.lang.ArrayIndexOutOfBoundsException: -32735

Here's the relevant code:

<cfset xls = spreadsheetNew()>

<cfset spreadsheetAddRow(xls, arrayToList( qryTest.getMeta().getColumnLabels() ))>

<cfset SpreadsheetFormatRow(xls, {bold=true,fgcolor="brown",color="white"}, 1)>

<cfset SpreadsheetAddRows(xls, qryTest)>

<cfheader name="Content-Disposition" value="attachment; filename=#filename#">

<cfcontent variable="#spreadsheetReadBinary(xls)#" reset="yes" type="application/vnd.ms-excel">
