Vector dimension 0 does not match the dimension of the index 3072

Using Pinecone w n8n, and I get this message. I’m using the gemini experimental embedding model, 03-07 or something. Now according to other posts here, this type of error message is due to a mismatch in dimensions. However, I’ve been pretty thorough and 3072 is the dimensions mentioned on MTEB. all the entries are empty when i check what was attempted to be placed in my index. please help ts bug lowkey annoying. i did not have this issue when using geminis 004 embeding model

Welcome to the Pinecone community forums @fleurmmii

I had a quick look at the Gemini Embedding Experimental. The page states

Output dimension size
Elastic, supports: 3072, 1536, or 768

Assuming that’s possible in n8n, please double-check that you’ve configured it correctly.

This post suggests the default dimension size differs from what you expect.
