ERROR FAISS Vector Store Creator

I am running a KNIME sample process about generating a local Vector Store and the FAISS Vector Store Creator node is running errorly. The error message is ''ERROR FAISS Vector Store Creator 3:2858 Execute failed: Error code: 400 - {‘error’: {‘message’: ‘invalid input type’, ‘type’: ‘api_error’, ‘param’: None, ‘code’: None}}“

When I use Chroma Vector Store Creator, I am running into the same error:“ERROR FAISS Vector Store Creator 3:2858 Execute failed: Error code: 400 - {‘error’: {‘message’: ‘invalid input type’, ‘type’: ‘api_error’, ‘param’: None, ‘code’: None}}”

The input model is OpenAI Embeddings Connector, and the settings are as shown in the figure:

The text data is in the example without any changes.

Hope to get help from the sample author @Vittorio Haardt and @Roberto Cadili , thanks
