node.js - ESOCKETTIMEDOUT Cloud Functions for Firebase -


i using cloud functions firebase firebase realtime database in order data management app.

one of functions though seems terminated since takes 100-150 seconds complete. happens error : esockettimedout.

is there way prevent this?

here function:

function gettopcarsforuserwithpreferences(userid, genres) {   const pathtocars = admin.database().ref('cars');    pathtocars.orderbychild("istop").equalto(true).once("value").then(function(snapshot) {        return writesuggestedcars(userid, genres, snapshot);   }).catch(reason => {     console.log(reason)   }) }  function writesuggestedcars(userid, genres, snapshot) {     const carstowrite = {};     var snapcount = 0     snapshot.foreach(function(carsnapshot) {         snapcount += 1         const cardict = carsnapshot.val();         const cargenres = cardict.tacargenre;         const genre_one = genres[0];         const genre_two = genres[1];          if (cargenres[genre_one] === true ||cargenres[genre_two] == true) {             carstowrite[carsnapshot.key] = cardict     }          if (snapshot.numchildren() - 1 == snapcount) {             const pathtosuggest = admin.database().ref('carssuggested').child(userid);             pathtosuggest.set(carstowrite).then(snap => {              }).catch(reason => {             console.log(reason)              });         }     }); }

the gettopcarsforuserwithpreferences gets called when user adds preferences. cars table has 50k entries.

well need return everytime use async task.

edit: return 'writesuggestedcars' think never returns value. not have compiler, thought return promise.resolved(). can insert putted 'here'?

maybe work:

function gettopcarsforuserwithpreferences(userid, genres) {   const pathtocars = admin.database().ref('cars');    return pathtocars.orderbychild("istop").equalto(true).once("value").then(function(snapshot) {        return writesuggestedcars(userid, genres, snapshot);   }).catch(reason => {     console.log(reason)   }) }  function writesuggestedcars(userid, genres, snapshot) {     const carstowrite = {};     var snapcount = 0     snapshot.foreach(function(carsnapshot) {         snapcount += 1         const cardict = carsnapshot.val();         const cargenres = cardict.tacargenre;         const genre_one = genres[0];         const genre_two = genres[1];          if (cargenres[genre_one] === true ||cargenres[genre_two] == true) {             carstowrite[carsnapshot.key] = cardict     }          if (snapshot.numchildren() - 1 == snapcount) {             const pathtosuggest = admin.database().ref('carssuggested').child(userid);             return pathtosuggest.set(carstowrite).then(snap => {                 // 'here' think return promise/promise.resolve() work             }).catch(reason => {             console.log(reason)              });         }     }); }
