I am trying to parse lots of data from external API endpoint to my Database, I keep getting error 429.

I've tried timeout and sleep lib but it doesn't work for some reason.

Here is the code :

async function(req, res) {
    console.log("usa sam");
    try {
        let count = await Subjekti.estimatedDocumentCount();
        let response = await axios.get(`x/?offset=${count}&limit=5000`, {
            timeout: 5800,
            headers: {
                "Key": "x"
            }
        });
        const subjects = response.data;
        for (let subject of subjects) {
            let panyDetails = await axios.get(`=${subject.mbs}&expand_relations=true`, {
                headers: {
                    "Key": "x"
                }
            });
            await Subjekti({
                mbs: subject.mbs,
                sud_id_nadlezan: subject.sud_id_nadlezan,
                sud_id_sluzba: subject.sud_id_sluzba,
                oib: subject.oib,
                ino_podruznica: subject.ino_podruznica,
                stecajna_masa: subject.stecajna_masa,
                datum_osnivanja: subject.datum_osnivanja,
                postupak: subject.postupak,
                likvidacijska_masa: subject.likvidacijska_masa,
                skracene_tvrtke: panyDetails.data.skracene_tvrtke && panyDetails.data.skracene_tvrtke.length > 0 ? panyDetails.data.skracene_tvrtke[0].ime : null,
                ulica: panyDetails.data.sjedista && panyDetails.data.sjedista.length > 0 ? panyDetails.data.sjedista[0].ulica : null,
                kucni_broj: panyDetails.data.sjedista && panyDetails.data.sjedista.length > 0 ? panyDetails.data.sjedista[0].kucni_broj : null,
                naziv_naselja: panyDetails.data.sjedista && panyDetails.data.sjedista.length > 0 ? panyDetails.data.sjedista[0].naziv_naselja : null,
                naziv_zupanije: panyDetails.data.sjedista && panyDetails.data.sjedista.length > 0 ? panyDetails.data.sjedista[0].naziv_zupanije : null,
            }).save();
            console.log("spremija i cekam");

        }
    } catch (err) {
        //Baci error 500...
        return apiResponse.ErrorResponse(res, err);
    }
}

Looking forward to your reply.

Try using debounce approach in this case to avoid sending too many requests.

see an example here : https://www.freecodecamp/news/javascript-debounce-example/

Ive found out solution:

await new Promise(resolve => setTimeout(resolve, 5000));

Hope it helps someone and save you time.

You are sending too many requests, and you get ratelimited.

You should change your logic to allow more data to be sent and retrieved with a single request, or delaying most part of your requests to a later stage.

To delay request using axios interceptors, take a look here:
