Apache Pinot

I am getting error in prestodb when running the following query.
```select channel,
    sales_date,
    sum(sales) as sum_sales,
    sum(units) as sum_unts
from pinot.default.guestSlsLitm
where channel = 'WEB'
group by channel, sales_date
union all
select channel,
    sales_date,
    sum(sales) as sum_sales,
    sum(units) as sum_units
from pinot.default.guestSlsLitm
where channel = 'STORES'
group by channel, sales_date;```
Each of the individual queries work separately. but the union does not.
Even the explain plan fails with
```Query 20200825_180515_00000_mshj8 failed: Expected to find the pinot table handle for the scan node
com.facebook.presto.spi.PrestoException: Expected to find the pinot table handle for the scan node
