@hwchase17 appreciate your help here, please

The problem was that the embeddings model you were using was from OpenAI, but I am now using a hugging face embedding model (Sentence Transformers). By default, the pretrained models output embeddings with size 768 (base-models) or with size 1024 (large-models).
