The pdf report with manual tagging throws EmptyStackException

I have spring webapp where I am using JasperReports to generate some basic database query reports and exporting into pdf.

I have tried programmatically adding tags instead of using jrxml, with dynamic-jasper and that runs into different issue. My jrxml file is almost a copy of tabular-report.jrxml example from Jaspersoft Studio. Let me know if you need to look at something else to figure this out, any help is appreciated at this point.

Found this but it has no solution: https://community.jaspersoft.com/questions/1112221/error-manulal-tagging-table-pdf-export

Here is my jrxml file:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport ....>
    <style>....
    </style>
    <queryString>
        This works, deleted because its sensitive.
    </queryString>
    <field name="last_login" class="java.sql.Timestamp"/>
    <field name="first_name" class="java.lang.String"/>
    <field name="middle_name" class="java.lang.String"/>

The error is caused by the net.sf.jasperreports.export.pdf.tag.table=end property which is set on an element in the detail band in your report. The detail band repeats for each record in the query result, so setting net.sf.jasperreports.export.pdf.tag.table=end in the detail band doesn't make sense.

The property should be set on an element that prints only once at the end of the table/page, for instance in the page footer band:

<pageFooter>
    <band height="1">
        <textField>
            <reportElement x="0" y="0" width="100" height="1">
                <property name="net.sf.jasperreports.export.pdf.tag.table" value="end"/>
            </reportElement>
            <textFieldExpression>""</textFieldExpression>
        </textField>
    </band>
</pageFooter>
