Calling lambda recursively in sam local invoke

Question

How can I recursively call lambda inside itself in sam local environment?

const AWS = require('aws-sdk');
const lambda = new AWS.Lambda();

exports.foo = async(event, context) => {
  // .......
  lambda.invoke({ FuncitonName: context.functionName, InvocationType: 'Event', Payload: {/* .... */}})
}

This apparently does not work.

EDIT

My usecase is to split data to prevent timeout. Payload contains page number and this lambda fetches data from API with the page number and put it to DynamoDB. Returning result to caller is not important so async invocation is fine.

What is the point to call a lambda function recursively ? Could you describe your use case ? What is the output of your execution ? — Traycho Ivanov, Aug 17 '20 at 18:51
Actually, `lambda.invoke` is under guard condition. I omitted that for brevity — yskkin, Sep 27 '20 at 07:52

If you need to call other function I would recommend using localstack which has better support working with lambda functions locally and inter-calls between them.

sam local is fine if you work only with the function itself but once you have integration with s3, dynamodb, sqs, lambda better to use localstack
