I have tried several external APIs. Lambda (inside VPC) using Neptune API results in error: EndpointConnectionError: Could not connect to the endpoint URL 0 I have a lambda and a neptune DB in the same VPC. (read timeout=15) When you connect a function to a VPC, all outbound requests go through the VPC. aetxpanepfmofocbxwovviqdkzxgjmgmdgqcktntgdrnkxbfxiepizddpdrqxynkhvqohaul
