Download attachments via API

How to download attachments via API?
My code:
const fetch = require(‘node-fetch’);


async function addAttach(taskGid) {
    try {
        const attach = global.client.attachments.getAttachmentsForTask(taskGid, {opt_fields: "permanent_url"})
        .then((result) => {
            result.data.forEach((attach, name, index) => {
                setTimeout(() => download(attach.permanent_url), 300 * index)})
                 
   
        });
    } catch(e) {
        console.log(`Error addattach ${e}`);
    }
}

async function download(url) {
    const response = await fetch(url);
    const body = await response.body;
    return body
    
}

Response is:

<html><head><meta name="window" content="{&quot;clientVersion&quot;:&quot;c11912c228842823219b21d1bd6eeddae8b87791&quot;,&quot;recaptchaV2SiteKey&quot;:&quot;6LdkcuISAAAAAAbgBM_0ZV4dH2wVsq2Ck0jJRFdS&quot;,&quot;recaptchaEnterpriseSiteKey&quot;:&quot;6Lf1FtQZAAAAAKGsW3JoCdtQfzfCb2umWbEoyOjE&quot;,&quot;releaseRevision&quot;:&quot;20211123_221625_c11912c228842823219b21d1bd6eeddae8b87791&quot;,&quot;syncCluster&quot;:&quot;prod&quot;,&quot;userAgent&quot;:&quot;&quot;,&quot;loginConfig&quot;:{&quot;targetUrl&quot;:&quot;https://app.asana.com/app/asana/-/get_asset?asset_id=1201421973204556&quot;,&quot;signupUrl&quot;:&quot;https://asana.com/create-account&quot;,&quot;configName&quot;:&quot;prod&quot;,&quot;showSandLoginButtons&quot;:false,&quot;error&quot;:null,&quot;googleLastEmail&quot;:&quot;&quot;,&quot;googleSsoRequirements&quot;:[],&quot;samlTimeoutInfoIfLoginExpired&quot;:null,&quot;recentSamlEmail&quot;:null,&quot;recentSamlEmailDomain&quot;:null,&quot;forceEmail&quot;:&quot;&quot;,&quot;oauthActionUrl&quot;:&quot;https://app.asana.com/-/oauth2callback&quot;,&quot;extraGoogleAuthTokens&quot;:[],&quot;shareLinkKey&quot;:&quot;&quot;,&quot;shareLinkDomainId&quot;:&quot;&quot;,&quot;utm_campaign&quot;:&quot;&quot;,&quot;utm_medium&quot;:&quot;&quot;,&quot;utm_source&quot;:&quot;&quot;,&quot;enableCaptchas&quot;:true,&quot;showCaptchaCheckbox&quot;:false,&quot;showCaptchaScore&quot;:true,&quot;xsrfToken&quot;:&quot;5cbade8f16d57d8de4abdbb169d0f701:1637762036518&quot;,&quot;autoDetectLogin&quot;:false,&quot;translations&quot;:{&quot;14vqnjf&quot;:[0,&quot;Back&quot;],&quot;1jgonki&quot;:[0,&quot;Asana logo&quot;],&quot;6c7p6e&quot;:[2,&quot;This site is protected by reCAPTCHA and the Google &lt;privacylink&gt;Privacy Policy&lt;/privacylink&gt; and &lt;termslink&gt;Terms of Service&lt;/termslink&gt; apply.&quot;],&quot;1qwtlnx&quot;:[0,&quot;Log in with Google&quot;],&quot;1cymyzw&quot;:[0,&quot;or&quot;],&quot;5rjrso&quot;:[0,&quot;Don&#x27;t have an account?&quot;],&quot;rs0iwj&quot;:[0,&quot;Sign up&quot;],&quot;1pr4zrz&quot;:[0,&quot;Email address&quot;],&quot;1p2cgqu&quot;:[0,&quot;Password&quot;],&quot;xhq4e8&quot;:[0,&quot;Please enter a valid email address.&quot;],&quot;hem9g3&quot;:[0,&quot;Forgot your password?&quot;],&quot;r8w892&quot;:[0,&quot;Log in&quot;],&quot;ho39t5&quot;:[1,&quot;{googleSsoName} requires you to use a Google account from the {domain} domain.&quot;],&quot;1bf7ig9&quot;:[0,&quot;You must use a Google account from one of the following domains:&quot;],&quot;z65pvl&quot;:[0,&quot;Your account has been disabled.

Try to use the “download_url” instead of “permanent_url”.

Download_url is a temporary secure download link, that works for a few minutes or seconds.

So, I also suggestion to query that url just before downloading the file, using:
GET /attachments/{ID_ATTACHMENT}
because, if you query download_url for 1000 tasks, and you start download them one by one, some url may expire before you start your download.

If you try to download them from the browser client-side, you will certainly get CORS cross origin error.
You should download them from server-side, but I think that’s what you do, using “node-fetch”.
