Terms(Pie Chart) not loading in Banana Dashboard

[ifancytolearn]

I use solr/banana to integrate with my cassandra for search use case and analytics. I am trying to add a Terms(pie chart) in my banana dashboard. It seems that the pie chart loads only for cartid which is the partition key of my cassandra. If I use other index (e.g. location, carttype ) to display my pie chart, it does not load at all.

Attaching my solr config.

    <field indexed="true" multiValued="false" name="modelnumber" stored="true" type="StrField"/>
    <field indexed="true" multiValued="false" name="location" stored="true" type="StrField"/>
    <field indexed="true" multiValued="false" name="customer" stored="true" type="StrField"/>

</fields>
<uniqueKey>cartid</uniqueKey>

Can you please help?
