Actually i am not able to get the table names list of dynamodb by using dynamodb scala api

Kindly help me if anyone knows, where I have mistaken(i am trying to access AWS hosted dynamodb). below is the configuration {
host = “
port: 8001
region = “ap-south-1”
parallelism = 4
credentials {
access-key-id = “test”
secret-key-id = “test”

When i execute the code with above config,i get empty table names list.
kindly help if anyone knows.
