Fixes #1586. Re-lands the fix from #1922 (merged into release-0.5.1) on a branch pushed directly to this repo, so CI has access to the secrets forked PRs can't use — see #1814 for why the forked version's E2E checks could never pass. Applied by hand rather than cherry-picked because src/api/settings.py has since been split into the src/api/settings/ package on main; the endpoint change now lives in src/api/settings/endpoints.py. Includes a unit regression test asserting an invalid preset returns 400, not 500.

Summary by CodeRabbit

  • Bug Fixes
    • Preserves the original error status when an invalid preset is submitted, so bad input continues to return a 400 response.
    • Unexpected failures now return a consistent 500 response with a clearer, fixed message instead of exposing internal error details.
  • Tests
    • Added coverage for invalid preset handling to confirm the correct error code and message are returned.

Walkthrough

Exception handling in update_docling_preset was changed so HTTPException is re-raised unchanged, preserving its original status code, while non-HTTP exceptions are logged and converted to a generic 500 error. A new unit test validates that invalid presets return a 400 status.

Changes

Layer / File(s) Summary
Exception handling fix and test
src/api/settings/endpoints.py, tests/unit/api/test_settings_endpoints.py
update_docling_preset re-raises HTTPException unchanged and returns a fixed-detail 500 for other exceptions after logging; a new async test verifies an invalid preset raises HTTPException with status 400 and detail mentioning "Invalid preset" and the preset value.

🐰 A preset gone wrong, once lost in the fray,
Now wears its true four-hundred, come what may,
A test stands guard against the five-hundred veil,
Ensuring no mistake will hide the trail. 🥕

(cherry picked from commit effaf02)

* style: ruff autofix (auto)

* fix: remove duplicate test definitions from main merge

The automated merge-from-main on this branch concatenated two tests
(test_connector_processor_indexes_cleaned_filename,
test_langflow_connector_processor_uses_cleaned_filename) that already
existed under both names, tripping ruff F811. Keep one copy of each,
preferring the version wired with connector_id_exists=True to match
current check_document_exists behavior.

* fix: Ingestion of buckets not working right after connection is tested - CPD #75506 (#1942) (#2019)

* fix: update bucket ingestion messages for clarity and consistency

* fix: guard bucket pre-selection against connection ID mismatch

The defaults query returns the first S3/COS connection regardless of active
status. Only pre-select saved bucket_names when the defaults connection_id
matches the current connector.connectionId to avoid seeding the wrong
buckets if a stale connection exists alongside the active one.



* fix: prevent defaults from overwriting user bucket selections

Two issues in the initial-selection effect:
1. hasAppliedInitial was only set when valid buckets were found, leaving the
   effect live across bucket refreshes and allowing stale defaults to overwrite
   selections made after a refetch.
2. No guard against the async race where buckets loads before initialSelectedBuckets:
   user clicks buckets, defaults arrive later and silently overwrite them.

Fix: mark hasAppliedInitial unconditionally on first evaluation, and only apply
defaults when selectedBuckets is still empty (user hasn't acted yet).
