I'm currently creating a Dialogflow chatbot in nodejs and upon deploying my code I get an error message. I've attempted to uncomment most things out to just be left with the base functioning code and I am still unable to get it working. I'm not exactly sure what the issue is here
'use strict';
import {getAPIresponse} from "./api/index.js";
// const http = require('https');
// const respond = fulfillmentText => {
// return {
// statusCode: 200,
// body: JSON.stringify({
// fulfillmentText
// }),
// headers: {
// "Content-Type": "application/json"
// }
// }
//
// };
module.exports.dining = async (event,context) => {
const incoming= JSON.parse(event.body).queryResult;
console.log(`INCOMING: ${incoming.parameters.hall}`);
const {
displayName
} = incoming.intent;
console.log(displayName);
//const menu = getAPIresponse('https://esb.prod.uds.harvard.edu/api/dining/2.0/','events?locationId=36');
//console.log(menu);
// if(displayName === 'dining'){
// if(incoming.parameters.meal === 'breakfast'){
// //get's dining hall code to include in API request
// const hall = getCode(incoming.parameters.hall);
// //generate response from API based off of parameters passed by user
// const menu = getAPIresponse("https://esb.prod.uds.harvard.edu/api/dining/2.0/","events?locationId=${hall}", hall);
// console.log(menu);
// }
// if(incoming.parameters.meal === 'lunch'){
// //get's dining hall code to include in API request
// const hall = getCode(incoming.parameters.hall);
// //generate response from API based off of parameters passed by user
// const menu = getAPIresponse("https://esb.prod.uds.harvard.edu/api/dining/2.0","/events", hall);
// }
// if(incoming.parameters.meal === 'dinner'){
// //get's dining hall code to include in API request
// const hall = getCode(incoming.parameters.hall);
// //generate response from API based off of parameters passed by user
// const menu = getAPIresponse("https://esb.prod.uds.harvard.edu/api/dining/2.0","/events", hall);
// }
// }
};
Almost everything is commented out and I still get the error message that reads

AWS Lambda does not support the ES6 import
specifier as you've written here
import {getAPIresponse} from "./api/index.js";
because the ES6 import
syntax isn't yet supported by default in Node.js (note: my lambda runtime was set to Node.js 10.x).
Illustration:
I was having this issue as well when importing a library at the top of my lambda distribution's index.js
file.
The stacktrace Uncaught Exception { "errorType":"Runtime.UserCodeSyntaxError", ... unexpected token import found ... blabla... } ...
was thrown in my lambda function when I used the import
syntax:
import awsServerlessExpress from 'aws-serverless-express';
exports.handler = (event, context) => {
console.log('hello world!')
};
But not in this version below when I just used the standard module require
syntax.
const awsServerlessExpress = require('aws-serverless-express');
exports.handler = (event, context) => {
console.log('hello world!')
};
For me, it was the import
syntax that was causing the SyntaxError
exceptions, but do take note that, for you, any JavaScript syntax not supported by your current Node.js runtime will throw this exception.
A couple of solutions:
Change all import
statements to standard module require
statements and keep using whatever default JavaScript flavour is supported by your configured Node.js runtime.
Use a transpiler like Babel w/ Webpack to transpile your ES6 JavaScript before deploying to the cloud.
Use the quick solution nicely described by Yitzchak below :) Just bump the NodeJS version on your Lambda Dashboard.
