Serverless invoke local function with mock has no output

I am following this tutorial here:

I’ve hit a wall where after I refactor my code I am not able to see the output anymore.
Not even console.logs.

Here is my serverless function for get:

import * as dynamoDbLib from "./libs/dynamodb-lib";
import { success, failure } from "./libs/response-lib";

export async function main(event, context){
  const params = {
    TableName: process.env.tableName,
    // 'Key' defines the partition key and sort key of the item to be retrieved
    // - 'userId': Identity Pool identity id of the authenticated user
    // - 'noteId': path parameter
    Key: {
      userId: event.requestContext.identity.cognitoIdentityId,
  try {
    const result = await"get", params);
    if (result.Item) {
      // Return the retrieved item
      return success(result.Item);
    } else {
      return failure({ status: false, error: "Item not found." });
  } catch (e) {
    return failure({ status: false });

And my code for the failure and success response in response-lib.js:

export function success(body) {
  return buildResponse(200, body);

    export function failure(body) {
      return buildResponse(500, body);

    function buildResponse(statusCode, body) {
      return {
        statusCode: statusCode,
        headers: {
          "Access-Control-Allow-Origin": "*",
          "Access-Control-Allow-Credentials": true
        body: JSON.stringify(body)

I am on OSX Mojave
And have this serverless version:

Framework Core: 1.67.0

Plugin: 3.5.0

SDK: 2.3.0

Components: 2.22.3
