InitiatorDtoLambda.ts

import { Lambda } from 'aws-sdk';
import { UserDto } from './UserDto';
import { GreetingDto } from './GreetingDto';

const lambda = new Lambda({
  apiVersion: '2015-03-31',
  region: 'us-east-1',
});

export const handler = async (event: any) => {
  const userDto = new UserDto('Arian', 'Acosta', false);

  const params = {
    FunctionName: "GREETING_LAMBDA_ARN",
    Payload: userDto.serialize(),
  };

  const { Payload } = await lambda.invoke(params).promise();

  const greetingDto = GreetingDto.from(Payload);

  console.log(greetingDto.greeting); // TS autocompletes .greeting !
};
