API creation does not work without specifying full endpoint

[andreachild]

The utility does not work to create a graphQL API if the full graph endpoint is not provided. It is expected that if the graph name and region are supplied, the API should be created. There is no error message or output when the utility is executed.

Example:

amazon-neptune-for-graphql % neptune-for-graphql --create-update-aws-pipeline-region us-west-2 --create-update-aws-pipeline-neptune-database-name test-db-name --create-update-aws-pipeline --create-update-aws-pipeline-name test --output-resolver-query-https
amazon-neptune-for-graphql %
