I’m in mid of developing Genai app with

• private data stored in vertex ai vector db
• llm as gpt4
• langhain as orcestrator.

When I Invoke vector_store retrever I get error: OPENSSL_internal:CERTIFICATE_VERIFY_FAILED.

The vector store index is being created with same credentials.

Here is a sample code.

aiplatform.init(credentials=credentials, project=PROJECT_ID, location=REGION, staging_bucket=BUCKET_URI)
my_index = aiplatform.MatchingEngineIndex.list()[0]
my_index_endpoint = aiplatform.MatchingEngineIndexEndpoint.list()[0]
embedding_model = VertexAIEmbeddings(model_name="textembedding-gecko@003")
vector_store = VectorSearchVectorStore.from_components(
    project_id=PROJECT_ID,
    region=REGION,
    gcs_bucket_name=BUCKET,
    index_id=my_index.name,
    endpoint_id=my_index_endpoint.name,
    embedding=embedding_model,
)


# Initialize the vectore_store as retriever
retriever = vector_store.as_retriever()
# perform simple similarity search on retriever
result = retriever.invoke("What are my options in breathable fabric?") #<<<<<ERROR here
