Get js errors from the site

I try to get js errors from the sites:

CDP(async (client) => {
    const {Log, Page, Runtime, Network, Console} = client;
    try {
        await Network.enable();
        await Page.enable();

        await Log.enable();
        await Log.clear();
        Log.entryAdded(({entry}) => {
            console.log(entry);
            /*if (entry.level === 'error' && entry.source === 'javascript') {
                console.log(entry);
            }*/
        });

        await Console.enable();
        await Console.clearMessages();
        Console.messageAdded(({entry}) => {
            console.log(entry);
            /*if (entry != undefined && entry.level === 'error' && entry.source === 'javascript') {
                console.log(entry);
            }*/
        })

        await Page.navigate({url: url});
        await Page.loadEventFired();

        //console.log(html);
    } catch (err) {
        console.error(err);
    } finally {
        client.close();
    }

})

But methods Log.entryAdded and Console.messageAdded don’t want to give errors from some sites, for example - crucial.com.au or note.ly And Console.messageAdded - just returns undefined.

Perhaps someone knows how to get js errors correctly? Thanks.

Is Chrome running in a container? NO

According to that thread the solution is using Runtime.exceptionThrown and it actually works for me:

const CDP = require('chrome-remote-interface');

CDP(async (client) => {
    const {Page, Runtime} = client;
    try {
        await Page.enable();
        await Runtime.enable();
        await Page.navigate({url: 'http://note.ly'});
        // this needs to be registered after the page load command in order to
        // avoid showing exceptions from the previous page state
        Runtime.exceptionThrown((params) => {
            console.log('>', params);
        });
        await Page.loadEventFired();
    } catch (err) {
        console.error(err);
    } finally {
        client.close();
    }
});
