I’ve heard through the grapevine that there is an issue with Chroma Vector Store Reader node not working in v5.2.5 of the AP, and that this bug was rectified in 5.2.6. It is my experience that it in fact does not work with Chroma Vector Stores and, unfortunately, I’m not in a position to upgrade to 5.2.6 or 5.3 at the moment due to other constraints. (It is worth noting however that when I create a smaller test Chroma vector store in KNIME and save it as a *.model file, then connect the model file in via the Vector Store to Tool node, it works just fine!?)
Here is my problem: I have a rather larger Chroma vector store, made outside of KNIME using langchain and python, that I want to add to the RAG in my KNIME workflows. It is not an option for me to re-make this in KNIME using FAISS Vector Store Creator due to the size of the resource and cost of additional embedding.
Are there any solution to add this to my RAG, despite the current issues with Chroma Vector Store Reader in v5.2.5?
