SyntaxError: await is only valid in async function with Apify Metamorph

Question

I am trying to get my hands on Apify's Actor Metamorph with a very simple example :

const Apify = require('apify');
const request = require('request-promise');

Apify.main(async () => {

    const newInput = {
        startUrls: [{url: "http://example.org"}],
        pageFunction: () => {
            const title = await page.title();
            console.log(title);
        }
    };

    await Apify.metamorph('apify/web-scraper', newInput);

});

However the run fails with a syntax error :

SyntaxError: await is only valid in async function

How do I pass the async nature of pageFunction to the apify/web-scraper through Metamorph ?

Answer 1

Just put the async keyword in front of the function:

pageFunction: async () => {
    const title = await page.title();
    console.log(title);
}
