Q:

How to see console.log statements in deployed Lambda function

I'm getting started trying to write a lambda function with node and puppeteer. I'm using the serverless framework
I've been trying to follow https://codissimo.sinumo.tech/2019/12/27/serverless-puppeteer-with-aws-lambda-layers-and-node-js/ to utilize the provisioned chrome at https://github.com/shelfio/chrome-aws-lambda-layer . My function is working as expected locally.
my handler.js contains:
module.exports.main = async event => {
    console.log('IN HANDLER');

  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'main function executed!',
        input: event,
      },
      null,
      2
    ),
  };

my index.js contains a longrunning (45- 60 seconds) puppeteer function (main ) which returns an array of objects:
async function main(event, context, callback) {
  const chromium = require('chrome-aws-lambda');

 ...................................

 var obj_arr = [];
  var keys = head[0];
  for (let index = 0; index < body.length; index++) {
    var row = body[index];
    var obj = {};
    for (let i = 0; i < keys.length; i++) {
      var k = keys[i];
      obj[k] = row[i];
      console.log(obj);

    }
    obj_arr.push(obj);

  };

  console.log(obj_arr);
  return obj_arr;

After uploading my function to lambda using  serverless framework without error. I followed the directions at the bottom of the article about testing the pre provisioned chrome in my layers dashboard. As you can see in the screenshot it appears to be working correctly.
being brand new to this I don't understand the log output:

I get a similar log output when I run my deployed function through the api gatewaybut I don't see either the console.log In my function locally I am able to see console.log statements or the returned array of objects which I see when I run locally. How to I see those in my deployed lambda function when I run it?
EDIT:
I've added a screenshot of what I think you are referring to.  I don't see the console logged output I see locally. Can you explain further or am I looking in the wrong place?

Edit3:
I changed the handler to :
'use strict';
var index = require('./index.js');

module.exports.main = async event => {
  var res = await index.main();

  console.log('hello');
  console.log(res);

  console.log('IN HANDLER');
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'main function executed!',
        input: event,
      },
      null,
      2
    ),
  };

};

Now seeing error messages.

A:

The logs written to CloudWatch by your Lambda function seem to be Base64 encoded and compressed with the gzip format. This looks like the behavior of the serverless enterprise plugin after issues regarding high costs for CloudWatch were opened.
To retrieve the original logs, you can try running the following Node.js code and pass in the encoded log string.
function getReadableLogs(encodedLogs) {
    const decodedLog = Buffer.from(encodedLogs, 'base64'); // Decode log data
    const parsed = JSON.parse(zlib.gunzipSync(decodedLog).toString('utf8')); // Decompress log data
    return parsed;
}
