I'm having issue using a the nomic-embed-text model with ollama. I've updated the embedding dimensions to 768 per nomic documentation. However, whenever I try to ingest data I get this error

I've updated the embedding dimensions to 768 per nomic [documentation](https://docs.nomic.ai/platform/embeddings-and-retrieval/text-embedding).

Thanks for reporting! The only current workaround would be to ingest content with the default embedding dimensions, and then switch. I’ll get to fixing this at the end of the weekend!

I've now implemented a fix in commit b7344644dc, and it should be in the latest release
