Unexpected token function in Cloud9 AWS Lambda - amazon-web-services

Question

I am trying the async/await approach in AWS lambda function with node v8.11.3 npm v5.10.0. When I run it gives me the following response:
{
"errorMessage": "Unexpected token function",
"errorType": "SyntaxError",
"stackTrace": [
" ^^^^^^^^",
"SyntaxError: Unexpected token function",
"createScript (vm.js:56:10)",
"Object.runInThisContext (vm.js:97:10)",
"Module._compile (module.js:542:28)",
"Object.Module._extensions..js (module.js:579:10)",
"Module.load (module.js:487:32)",
"tryModuleLoad (module.js:446:12)",
"Function.Module._load (module.js:438:3)",
"Module.require (module.js:497:17)",
"require (internal/module.js:20:19)"
]
}
The lambda function is:
const fetch = require('node-fetch')
exports.handler = async function(event,context)
{
console.log(event);
let img = await
fetch(`https://catappapi.herokuapp.com/users/${event.userId}`);
let parseddata = await img.json()
console.log(parseddata.imageUrl);
}
How to solve this issue?

You are getting this error because you are running an older version of nodejs in cloud9 environment process (can verify that by console.log(process.version) which would be different than node --version). Follow these steps to update the process node in your Cloud9 environment:
nvm install 11
nvm use 11
nvm alias default v11
