BUG FIX: Resolve "Ambiguous reference to column name" error in get_samples_at_geo_cord_location_via_sample_event()
Problem:
- Query requested s.description, s.thumbnail_url, s.alternate_identifiers
- These columns don't exist on MaterialSampleRecord nodes
- thumbnail_url exists on both 'event' and 'site' tables, causing ambiguity
- Query was failing silently, returning empty array []
Solution:
- Use only columns that exist on MaterialSampleRecord: pid, label, name
- Add event.pid to match Path 1/2 queries
- Remove thumbnail_url sorting (column doesn't exist on samples)
- Simplify ORDER BY to just sample_label
Testing:
- Verified Path 1 and Path 2 queries work (they use correct columns)
- Error found via browser console: document.getElementById('loading_combined').innerHTML
- Error was: "Binder Error: Ambiguous reference to column name 'thumbnail_url'"
Changes:
- Removed: s.description, s.thumbnail_url, s.alternate_identifiers
- Added: s.name, event.pid (matching working queries)
- Updated documentation to reflect actual returned columns

Bugfix for Cesium Click Query
Fixes bug introduced in PR #27 where the combined samples query was failing silently.
Problem
The
get_samples_at_geo_cord_location_via_sample_event()function was requesting columns that don't exist on MaterialSampleRecord nodes:s.descriptions.thumbnail_url(exists on event/site, causing ambiguity error)s.alternate_identifiersThis caused a DuckDB binder error: "Ambiguous reference to column name 'thumbnail_url'"
Result: Query returned empty array
[]while Path 1 and Path 2 queries worked correctly.Solution
pid,label,nameevent.pidto match Path 1/2 structureTesting
This is a critical fix - without it, the combined query feature doesn't work at all.
