Error: Could not connect to the endpoint URL https:dynamodb.singapore.amazonaws.com
Answered by Rafal Wilinski

Solution
dynamodb.singapore.amazonaws.com is not a valid DynamoDB regional endpoint. Singapore's Region code is ap-southeast-1. Configure that Region and let the SDK resolve the correct service endpoint.
aws dynamodb list-tables --region ap-southeast-1
The standard regional hostname is dynamodb.ap-southeast-1.amazonaws.com. Remove an incorrect custom endpoint override. If connection failures continue, check DNS, proxy settings, outbound HTTPS and any VPC endpoint policies rather than changing table keys.
Use the official DynamoDB endpoints list for partition-specific, FIPS or dual-stack endpoints.
