Change your mapping.xml file as follows:
from:
<field name="values" type="strings" direct="true">
<bind-xml name="values" node="element"/>
</field>
to:
<field name="values" type="string" collection="array" direct="true">
<bind-xml name="values" node="element"/>
</field>
I am not sure why "strings" isn't be flagged as an invalid type. But if
you change your mapping, it will work properly as I just ran your test
case here.
