404 Client Error with HuggingFace Embeddings Connector

KNIME Analytics Platform
1

I am implementing RAG with HuggingFace and FAISS Vector Store. The workflow was working 2 weeks ago but now throws an error Execute failed: 404 Client Error: Not Found for url: https://api-inference.huggingface.co/pipeline/feature-extraction/sentence-transformers/all-MiniLM-L6-v2 (Request ID: Root=1-68246117-1de5875d1e56505b6b0acdf8;5de437b4-290c-4a53-9eed-96b3e6e267a6)
Steps I have checked:

  1. Different HF embedding models.
  2. The workflow for HF LLMs works properly with the same HF User Access Token.
  3. I have tested with Chroma Vector Store and TextEmbedder Node and both throw the same error.
  4. I have tested with different HF accounts.
  5. I have tried all the combinations of the parameters.

Please provide a resolution. It looks like there was an update to either HuggingFace or KNIME which has caused this issue. The issue is most likely that the API URL has changed. The URL that the nodes are using is different from the URL on the HuggingFace Hub.

Hi there @Nihal_K_P -

Thanks for the detailed error message and list of steps tried so far. I have asked our AI developers internally to investigate further.

Hi again -

I heard from one of our senior devs that we have a ticket open for this (AP-24318) - so we’re working on it. I don’t have an ETA at the moment, but once we know more I can update you here.
