async function does not work in a plugin

Mikael 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!

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)

Mikael 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.

Mikael Jenkler

Hehe, true true

Mikael Jenkler

Works great in 8.x now
