[SachinS]

I have a table look which has around 15 columns and for two of the measures I have put drilldown to show the summaries related to data, but getting this weird error , while data is available in bigquery and able to see that summaries by creating one more small table below , but inisde the drill down it is giving this issue  and the same drilldown is working for other set of rows

Hi Sachin - this definitely looks like a bug and I would encourage you to report it to Looker Support.
