[BUG] Upsert - Error: vectorsService.upsertVector - Error: TypeError: Cannot read properties of undefined (reading '0')

[ApplicationError]

Describe the bug
Error: vectorsService.upsertVector - Error: TypeError: Cannot read properties of undefined (reading '0')

I've setup a new Flowise project with the following components & configuration:

Conversational Retrieval QA Chain

• Chat Model
  -- GroqChat (Model Name: llama-3.1-405b-reasoning)
• Vector Store Retriever
  -- Pinecone
  --- Embeddings
  ---- VoyageAI Embeddings (Model name: voyage-2)
  --- Document
  ---- Pdf File (.pdf file)
  ---- File Loader (.txt file)
  --- Text Splitter (Chuck Size: 1000, Chunk Coverlap: 200)

Check I go to "upsert" the data to Pinecone I get that error message.
Error: vectorsService.upsertVector - Error: TypeError: Cannot read properties of undefined (reading '0')

To Reproduce
Steps to reproduce the behavior:

1.) Setup as outlined above
2.) Save project
3.) Click on green "upsert" icon
4.) Click on green "upsert" button

Expected behavior
The data from the PDF and the TXT file to be stored in the Pinecone vector store.

Setup

• Installation: Render / Docker
• Flowise Version: 2.0.7

If you switch to other embeddings model it should works. Seen this issue with voyage embeddings, mostly due to the rate limit

Thank you very much for the reply. Do you have any recommendations for embedding models that would work best?

[Vortigern-source]

I have a similar issue, Im not sure what embedding to use with groq if VoyageAI isnt working the best

[Vortigern-source]

What embeddings can be used that are free? Also are you saying that reducing the rate limit option should fix it?

I have a similar setup (except using in-memory vector store) and the exact same error message.

I changed to OpenAI embeddings and it didn't fix the issue, still getting the same error message

Same issue here. I changed to OpenAI embeddings and it didn't fix the issue, still getting the same error message
