In many cases, the Compass schema analysis will display a bar chart for int32 fields. Clicking on a bar correctly generates the range query for that bar.

Sometimes, the schema analysis shows a selection of individual values for the int32 field. In Compass 1.12.0, clicking one of those individual values generates an incorrect query in the filter bar similar to:

{passenger_id: NumberInt{'[object Object]')}

When this happens, the "Filter" label turns red and "Analyze" button is greyed out and blocked.
