Fixes #7282

Summary

get_uploader is documented to return None for an unsupported provider, and every caller branches on if uploader is None. Two fallthrough paths ran a bare raise with no active exception, so an unknown provider, and a Bedrock provider without CREWAI_BEDROCK_S3_BUCKET configured, raised RuntimeError: No active exception to reraise instead of returning None.

This returns None in both paths and widens the return types to ... | None so it stays mypy-strict clean. The except ImportError re-raises (a provider SDK is not installed) are intentionally unchanged.

Verification

Tests added or updated for the changed behavior
Relevant tests and quality checks pass locally

Added lib/crewai-files/tests/test_factory.py covering the unknown-provider and unconfigured-Bedrock paths. Verified both raised RuntimeError: No active exception to reraise before the change and return None after. mypy (strict config) and ruff check / ruff format pass on the changed files.

None

Uploader fallback behavior

Layer / File(s)	Summary
Factory contract and fallback paths `lib/crewai-files/src/crewai_files/uploaders/factory.py`	`get_uploader` return types now include `None`. The function returns `None` for unsupported providers and for Bedrock configurations with missing or falsy bucket names.
Fallback regression coverage `lib/crewai-files/tests/test_factory.py`	Tests verify `None` for unknown providers and missing, `None`, or empty Bedrock bucket names.

Merge Risk: ⚪ Minimal · up to 784dd

Unsupported providers and unconfigured Bedrock uploads now return None rather than failing with a bare re-raise, with tests covering the intended fallback cases. No current merge-blocking risk remains.

get_uploader is documented to return None for an unsupported provider, and every caller branches on `if uploader is None`. Two fallthrough paths ran a bare `raise` with no active exception, so an unknown provider and a Bedrock provider without a configured S3 bucket raised "RuntimeError: No active exception to reraise" instead of returning None. Return None in both paths and widen the return types to `... | None`. The Bedrock "not configured" guard now treats a falsy bucket_name (None or "") as unconfigured, not only an absent one. The except ImportError re-raises are unaffected. Fixes crewAIInc#7282

SWAPI03 · 2026-09-05T08:37:22Z

Thanks, good catch. Addressed in 784dd3c: the Bedrock config guard now keys on the value via not kwargs.get("bucket_name"), so an explicit None or empty-string bucket_name is treated as unconfigured, with a regression test covering both.
