If you start the local DynamoDB Docker instance without the -shareDb option, tables are not visible either to 
the 'aws dynamodb' cli or DynamodDB Workbench:

docker run -d -p 8000:8000 amazon/dynamodb-local

If you start with the -shareDb option needed to see the tables, the container ends immediately.

Per answer on this question https://stackoverflow.com/questions/63835658/can-not-find-table-using-nosql-workbench-for-dynamodb-when-connecting-to-dynamod
start with -shareDb and all other default options:
docker run -d -p 8000:8000 amazon/dynamodb-local -jar DynamoDBLocal.jar -sharedDb -dbPath .

If you call lambda.invokeAsync() from one lambda calling another, if the calling lambda completes/exits before the second
lambda has been successfully invoked then depending on the timing it's possible the second Lambda will not invoke sucessfully.

The SDK docs show calling invokeAsync with a callback:

const params = {
  "FunctionName": "fucntion-name-to-invoke",
  "InvokeArgs": JSON.stringify(payload-to-pass-to-lambda)
};
lambda.invokeAsync(params, function (error, result) {

By default, @Target on one type, eg for properties:
@Target(ElementType.FIELD)
public @interface ExamplePropertyAnnotation

Specifying multiple targets as a List of target types:
@Target( { ElementType.FIELD, ElementType.PARAMETER } )
public @interface ExamplePropertyAndParameterAnnotation

}
