fix(deps): pin langchain-community<0.4.2 for ragas ChatVertexAI import#337
Merged
Conversation
langchain-community 0.4.2 removed chat_models/vertexai.py but ragas 0.4.3 still imports ChatVertexAI from that path at module load time. Pin to <0.4.2 until ragas updates their import. Upstream: vibrantlabsai/ragas#2745 Assisted-by: Crush:claude-opus-4-6
