TypeError: Cannot read property 'callback' of undefined

[jeff-pal]

const { getCurrentInvoke } = require('@vendia/serverless-express')
app.get('/', (req, res) => {
  const { event, context } = getCurrentInvoke()

  res.json(event)
})

What is wrong about the code above? I'm getting the following error:

I am also getting this with a basic Express app (v4.17.1) + "@vendia/serverless-express": "^4.5.2",

server.js

const express = require('express');
const app = express();

// app setup

module.exports = app;

handler.js

const serverlessExpress = require('@vendia/serverless-express')
const server = require('./server');

module.exports = serverlessExpress({ server });

see the same issue "@vendia/serverless-express": "~4.8.0" + "express": "4.17.3", index.js

const { app } = require('./server/app');
const serverlessExpress = require('@vendia/serverless-express');
/**
 * Main entry point for the application
 */
 exports.handler =  serverlessExpress({ app} );

was lambda error { "errorType": "TypeError", "errorMessage": "Cannot read property 'callback' of undefined", "stack": [ "TypeError: Cannot read property 'callback' of undefined", " at getFramework (/var/task/node_modules/@vendia/serverless-express/src/frameworks/index.js:7:18)", " at configure (/var/task/node_modules/@vendia/serverless-express/src/configure.js:22:35)", " at Object.<anonymous> (/var/task/index.js:10:21)", " at Module._compile (internal/modules/cjs/loader.js:1085:14)", " at Object.Module._extensions..js (internal/modules/cjs/loader.js:1114:10)", " at Module.load (internal/modules/cjs/loader.js:950:32)", " at Function.Module._load (internal/modules/cjs/loader.js:790:12)", " at Module.require (internal/modules/cjs/loader.js:974:19)", " at require (internal/modules/cjs/helpers.js:101:18)", " at _tryRequireFile (/var/runtime/UserFunction.js:63:32)" ] }

same error in here

const serverlessExpress = require('@vendia/serverless-express');
const app = require('./serverless/main').server;
exports.handler = serverlessExpress({ app })

version: "@vendia/serverless-express": "4.8.0"

Change the handler.js to the following.

exports.handler = serverlessExpress({ app: app })
