Hey @EliWoo111! 👋 I'm here to help you with bugs, questions, or becoming a contributor. Let's squash those bugs together!

Yes, the Weaviate index name needs to have the first letter capitalized to avoid a KeyError in the langchain_community.vectorstores.weaviate module when using Langflow 1.0.17 and Weaviate 1.24.24. This is ensured by the _to_pascal_case function in the WeaviateVectorStore class, which capitalizes the first letter of the index name if it is not already capitalized ^[1].
