Problem with CAIXA route

Hi!

I am having a problem with my getLotofacilContests schedule function.

For some time, it worked perfectly, but nowadays, it starts to return errors.

The error is that I am receiving a 401 or 403 from the CAIXA website link.

But if I run the code on my local machine, it works perfectly!

Can you help me make the function work properly again? It is hard to make it run every day on my local machine.

My website:
https://lotoproweb.com.br/

Page for which I took the URL:
https://loterias.caixa.gov.br/Paginas/Lotofacil.aspx

The request that I need to access every day is:

Netlify has no direct control over what response you receive from the other server.

As you’re probably aware:
401 is Unauthorized
403 is Forbidden

How are you making the request within the function?
Is it identical to the curl?

This is how I am making the request:

const fetch = (...args) => import('node-fetch').then(({ default: fetch }) => fetch(...args));

// 3000 is just a contest number example
const responseContent = await (await fetch("https://servicebus2.caixa.gov.br/portaldeloterias/api/lotofacil/" + (3000), {
      "headers": {
        "origin": "https://loterias.caixa.gov.br",
        "accept": "application/json, text/plain, */*",
        "accept-language": "pt-BR,pt;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6",
        "sec-ch-ua": "\"Microsoft Edge\";v=\"123\", \"Not:A-Brand\";v=\"8\", \"Chromium\";v=\"123\"",
        "sec-ch-ua-mobile": "?0",
        "sec-ch-ua-platform": "\"Windows\"",
        "sec-fetch-dest": "empty",
        "sec-fetch-mode": "cors",
        "sec-fetch-site": "same-site"
      },
      "referrer": "https://loterias.caixa.gov.br/",
      "referrerPolicy": "strict-origin-when-cross-origin",
      "body": null,
      "method": "GET",
      "mode": "cors",
      "credentials": "omit"
    })).text();

I think the problem is not with the code.

I think it is something about the machine that is sending the request, because it is a public route, and no auth is required.

Is there a way that Netlify can help me in this case? Maybe changing the environment in which the function is running? A Brazilian one, maybe?

I doubt there is anything wrong with the machine making the request.
Auth being required also has no real bearing on it.
The destination server can respond to any request with any response/status that it likes.
Only that server would know precisely why it’s rejecting your requests.

Perhaps, I can’t advise on that though, as I don’t work for them.
You’ll need to wait for one of their staff to chime in.

The origin of the request certainly may be what is causing it to get rejected, it’d be worth trying.

Provided that scheduled functions run in the same regions as regular functions, then São Paulo is apparently a region that you can change to via self-service.

You can see the information and regions here:
https://docs.netlify.com/functions/optional-configuration/#region

sa-east-1 - South America (São Paulo)

You need to be on at least a Pro Plan to take advantage of it.

I have tried this, but it doesn’t work :cry:

In what way?

  • Do you have a Pro Plan?
  • If yes, did the function region not change?
  • If the region did change, did the caixa website still return 401/403 to your function?

Yes, same result…

I don’t know what else can I do to fix it…

And sorry for the delay.

@SamO @hillary @hrishikesh or someone else from Netlify employees team.

Can you help me with this?

I asked several very specific questions, but you’ve answered with effectively a single “Yes”.

Can you answer the questions I asked?

Doing so will help everyone understand exactly what the result has been.

I can only agree with @nathanmartin. Did you make an attempt to contact the server returning the 401/403? Not sure how we can help here. We cannot control the response sent by the other server.
