on peut utiliser await page.waitfornavigation() en cas d'erreur "execution context was destroyed"



For the request interception we can use a separate function :

page.on('request', async req => {

    if(
        // block font, media, images by default
        [ 'font', 'media', 'image', 'other' ].includes(req.resourceType())

        ||
        // block script if we disabled js
        // note : this is rarely used as most websites wont send scripts when js is disables
        ( use_js === false && req.resourceType() === 'script' )

    ) {
        // block request
        await req.abort() ;

        // log
        // console.log('blocked', req.resourceType(), req.url())
    }
    else {
        await req.continue();
    }
});



await page.setMaxListeners(0) ;

            async function intercept( req ) {

                if(
                    // block font, media, images by default
                    [ 'font', 'media', 'image', 'other' ].includes(req.resourceType())
                    ||
                    // block script if we disabled js
                    // note : this is rarely used as most websites wont send scripts when js is disables
                    ( use_js === false && req.resourceType() === 'script' )

                ) {
                    // block request
                    await req.abort() ;

                    // log
                    // console.log('blocked', req.resourceType(), req.url())
                }
                else {
                    await req.continue();
                }
            }

            // build event interception
            page.on('request', intercept ) ;

            console.log(page.listenerCount("data"))

            // remove listener when request closes
            req.on('close', function(){
                // console.log('closed')
                page.removeListener('request', intercept );
                page.removeAllListeners('request');
                // console.log('removed all listners')
            });
