processing. * feat: Enhance component handling in custom utils for better flexibility * refactor: Simplify component retrieval logic and enhance error handling * refactor: Remove unnecessary 'required_inputs' field from multiple starter project JSON files * refactor: Change error handling to warning for component instantiation failures * refactor: Improve component type checking in get_component_instance and run_build_config functions * refactor: Update subclass check for custom_component in run_build_config function * refactor: Update component name retrieval logic to prioritize class name * refactor: Replace settings service call with direct BASE_COMPONENTS_PATH in test_get_all * refactor: Update required inputs and improve model name info across starter projects

The check `isinstance(custom_component, Component)` followed by `type(custom_component) is not Component` causes the interpreter to potentially look up the type and MRO twice per call. - By storing `type(custom_component)` in `klass` and using `issubclass(klass, Component)`, you avoid having Python walk the MRO twice for the same object, which is subtly more efficient especially in tight loops and heavy use scenarios. - Using `issubclass()` on the object's type is semantically equivalent to `isinstance()`, except it also works for custom metaclass scenarios and is very slightly faster when type is already known. **All program logic and comments are preserved, only the relevant portion is optimized.** * ✨ (freeze.spec.ts): introduce new function addFlowToTestOnEmptyLangflow to enhance test coverage and improve test reliability * ✨ (freeze.spec.ts): increase timeout value for waiting for "built successfully" text to appear to improve test reliability * ✨ (freeze.spec.ts): refactor code to check if firstRunLangflow is greater than 0 before calling addFlowToTestOnEmptyLangflow 🔧 (generalBugs-shard-9.spec.ts): update tags in test case to include @workspace and @components ♻️ (generalBugs-shard-9.spec.ts): refactor code to remove unnecessary steps related to sidebar search and node handling 🔧 (store-shard-0.spec.ts): update test cases to be skipped and improve readability by using async arrow functions --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Co-authored-by: Jordan Frazier Co-authored-by: Jordan Frazier <122494242+jordanrfrazier@users.noreply.github.com> Co-authored-by: codeflash-ai[bot] <148906541+codeflash-ai[bot]@users.noreply.github.com> Co-authored-by: cristhianzl --- .../components/amazon/s3_bucket_uploader.py | 8 +- .../components/deactivated/amazon_kendra.py | 66 ++ .../json_document_builder.py | 23 +- .../{logic => deactivated}/listen.py | 0 .../langflow/components/deactivated/metal.py | 54 ++ .../components/deactivated/multi_query.py | 59 ++ .../{logic => deactivated}/notify.py | 0 .../retriever.py | 35 +- .../deactivated/vectara_self_query.py | 76 ++ .../vector_store.py | 16 +- .../langchain_utilities/__init__.py | 6 -
