Due to the Explore Field Picker Upgrade in version 7.12 (https://docs.looker.com/relnotes#upgraded_explore_field_picker), it’s now possible to add a field to the Explore directly from the Field Search results (via the + icon).
However, it seems that this feature is enabled for Filter-only Fields, which may cause SQL issues if added by an unaware user.
You’ll find attached an example where I have a parameter (therefore a filter-only field) that can be added via the search result box, causing a SQL error.
It can also be the case that I’m missing something. If that’s the case, can you please point it out?
