Vector Search Quickstart Error

I am following the Vector Search Quickstart Guide, https://cloud.google.com/vertex-ai/docs/vector-search/quickstart#install-sdk, and encountering an issue when trying to run the following query in Jupyter notebook: 

# run query
response = my_index_endpoint.find_neighbors(
deployed_index_id = DEPLOYED_INDEX_ID,
queries = [query_emb],
num_neighbors = 10
)

# show the results
for idx, neighbor in enumerate(response[0]):
print(f"{neighbor.distance:.2f} {product_names[neighbor.id]}")

However, every time I execute this, I receive the following error:

The above exception was the direct cause of the following exception:

I am not sure why this is.
