find_exceptions
Filter Langfuse traces to identify and debug production errors by retrieving only ERROR-level traces for pipeline failure analysis.
Instructions
Returns only traces whose level field equals ERROR.
Filtering is performed on the server before the response is returned — the result set contains error traces only, never a mix of levels.
Useful for surfacing pipeline failures and debugging production errors. Both time range parameters are optional. Omit them to search across all time. Pagination works the same way as fetch_traces.
