async function does not work in a plugin

[Jenkler]

This code works with plain nodejs but not when I have it in a plugin!

async function f3() {

  let Parser = require('rss-parser');
  let parser = new Parser();
  let feed = await parser.parseURL('http://www.fz.se/core/rss/fznews_rss20.xml').catch((err) => { console.error(err); });
  console.log(feed);
}

f3();

Why do I get this error?

Any tips would be great!

[Jenkler]

I am running nodejs v6.11.5.

Async functions are not supported by Node versions older than version 7.6. So, Need to update!

[PitaJ]

I suggest updating to the latest LTS (Node 10)

[Jenkler]

Latest LTS is 8.x not 10.x

https://nodejs.org/en/ <-- Check here

I will be updating to 8.x. Do we have a lot of issues with mongodb 3.6.x ???? Safe to update?

[PitaJ]

Yeah, but Node 10 will be LTS starting in October, so you may as well upgrade to it now.

[Jenkler]

Hehe, true true

[Jenkler]

Works great in 8.x now
