Overall looks fine, but I'd rather see a test that shows that passing w/r/t the README, as a nit: It might be nice to have a link to the documentation ( https://docs.aws.amazon.com/appsync/latest/devguide/resolver-mapping-template-reference-dynamodb.html ) on how resolver mappings work and how you're passing them under the hood. |
