When does this happen?

IF Database timeout error when fetching traces with tags and timestamp filter, especially on large projects.

How others solved it

THEN Always provide both `fromTimestamp` and `toTimestamp` parameters when querying traces to enable efficient index usage. Also ensure proper indexing on `project_id`, `trace_id`, and `tags` columns. Consider breaking complex subqueries into simpler steps if timeout persists.

When calling the traces API, include both time bounds:
  GET /api/public/traces?limit=1&tags=%5B%22document%22%5D&fromTimestamp=2025-03-01T00:00:00.00Z&toTimestamp=2025-04-01T01:00:00.00Z
