Pydantic 2.10+ (pydantic-core 2.27+) rejects None for the by_alias parameter in model_dump(), raising TypeError. Coerce None to False to match the v1 fallback path behavior.

Summary
pydantic-core2.27+) rejectsNonefor theby_aliasparameter inmodel_dump(), raisingTypeError: argument 'by_alias': 'NoneType' object cannot be converted to 'PyBool'NonetoFalsein the v2 path to match the existing v1 fallback behavior on line 157Context
This broke the Openlayer SDK when used with LangFlow 1.5.0 (which ships with Pydantic 2.10.6). The error occurs during
_build_request→model_dump→model.model_dump(by_alias=None).Test plan
model_dump()works with Pydantic 2.10+ (by_alias no longer raises TypeError)
