Cloud Functions for Firebase - getaddrinfo ENOTFOUND

Question

Trying to make a request to Paypal's API using PayPal-node-SDK

exports.requestPayment = functions.https.onRequest((req, res) => {     return new Promise(function (fullfilled, rejected) {         paypal.payment.create(create_payment_json, {}, function (error, payment) {             if (error) {                 rejected(error);             } else {                 console.log("Create Payment Response");                 console.log(payment);                 res.status(200).send(JSON.stringify({                     paymentID: payment.id                 })).end();                 fullfilled(payment);             }         });      }); }); 

but I'm constantly getting an error:

Error: getaddrinfo ENOTFOUND api.sandbox.paypal.com api.sandbox.paypal.com:443     at errnoException (dns.js:28:10)     at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:76:26) 

Things I've tried:

1. Making a request to a totally different host, still ENOTFOUND
2. Wrapping the request with cors(req,res, ()=>{...})
3. Prepending https:// to the host

What is the problem?

Answer 1

You'll need to be on a paid plan to make external API requests.

Firebase's Blaze plan (pay as you go) has a free allotment for Cloud Functions. https://firebase.google.com/pricing/

Answer 2

in my situation I had to wait and let what ever lag was happening pass. Now it's fine again.
