crash on add followers as besties - 'feedback_required'

[gameszaum]

Question

I made a simple application to add all my followers on the close friends, it worked on the beggining and already added 1300 followers as besties, but suddenly starts failing and I want to know how can I fix and improve this.

Ps: I implemented the 'batchCooldown' after crash on the first time.

        const ig = new IgApiClient();

        console.log("Generating device...");

        ig.state.generateDevice(process.env.IG_USERNAME as string);

        console.log("Logging in...");

        (async () => {
            await ig.account.login(process.env.IG_USERNAME as string, process.env.IG_PASSWORD as string);

            console.log("Logged in, fetching followers...");

            const followersFeed = ig.feed.accountFollowers(ig.state.cookieUserId);
            const followers = (await this.getAllItemsFromFeed(followersFeed));

            console.log(`Fetched ${followers.length} followers, adding as besties...`);
            console.log(" ")

            const batchSize = 5;
            let i = 0;
            let max = followers.length;
            let batchCooldown = 0;

            while (i < max) {
                if (batchCooldown >= 1000) {
                    batchCooldown = 0;

                    console.log("Batch cooldown reached, waiting 10 minutes...");

                    await new Promise(resolve => setTimeout(resolve, 600000));
                }
                const batch = followers.slice(i, i + batchSize);
                const pks = batch.map(follower => follower.pk);

                await ig.friendship.setBesties({ add: pks });

                const time = Math.round(Math.random() * 5000) + 1000;
                await new Promise(resolve => setTimeout(resolve, time));

                i += batchSize;
                batchCooldown += 1;
                console.log(`Added batch of ${batchSize} followers as besties. Progress: ${Math.min(i, max)}/${max} - (${Math.round(Math.min(i, max) / max * 100)}%)`);
            }
            console.log("Process ended, all followers were added as besties. 🎉");
        })();

I don't know whats 'feedback_required' means.
