PineconeClient error: 'not supported value type'

[Error: PineconeClient: Error calling upsert: Error: not supported value type]

I have a nodejs server where I read a PDF, split it and embed it before uploading it to Pinecone. This works with one PDF I have (which is small), but doesn’t work with another one (which is larger).

I get the above error, and I don’t know how to proceed debugging it with Pinecone?

If you’re using langchain, I had to upgrade langchain to 0.53 from 0.51 and that fixed it.

Yes, I worked with them to identify the issue (a null value) and the patched it. Thanks for the rapid response to the new release, I very much appreciate it!
