Pinecone : ector dimension mismatch when upserting embeddings to Pinecone from Make.com scenario

Hello,

My scenario pulls a text field from an Airtable record, sends it to an HTTP module that calls the OpenAI API to generate text embeddings, and then feeds those embeddings into a Pinecone vector database via the Upsert Vector module.

Insertion into Pinecone keeps failing. I’ve tested several configurations but can’t pin down the issue. The error returned is:

csharp

CopierModifier

RuntimeError [400] Vector dimension 1 does not match the dimension of the index 1536

The HTTP module does output embeddings, so I’m not sure where the dimension “1” is coming from.

Does anyone know how to resolve this mismatch or what might be mis-configured in Make.com?

Thanks in advance for any guidance!
