You can try the following.

Plain Text

vector_store = SupabaseVectorStore(
    postgres_connection_string=connectionString,
    collection_name="llama_demo",
)


# for second iteration when you have already created the indexes in the first run
index = VectorStoreIndex.from_vector_store(vector_store=vector_store)

Bonus Tip: You can also define service context globally so you do not have to add it everywhere.
