node.js - Firebase admin.auth().getUser(uid) hangs (NodeJS) -


i'm using admin.auth().getuser(uid) in firebase admin sdk (nodejs), in serverless project, , return result. though function returns result, lambda still doesn't terminate , have use ctrl+c end it.

here's full code of function (in typescript):

public getuser(uid: string): {   console.log('firebasemanager getuser method start');   const self: firebasemanager = this;   const promise: = self.getdeferred();    admin.auth().getuser(uid)   .then(function(userrecord: admin.auth.userrecord) {     console.log("successfully fetched user data:", userrecord);     promise.resolve(userrecord);   })   .catch(function(error: firebaseerror) {     console.log("error fetching user data:", error.errorinfo);     promise.reject('error getting firebase user ' + uid);   });    return promise.promise; }

is there i'm doing wrong?

note if comment out admin.auth().getuser(uid) block (and replace promise.resolve("ok")), function terminate properly. mean, doesn't hang (but it's bit useless ^^):

public getuser(uid: string): {   console.log('firebasemanager getuser method start');   const self: firebasemanager = this;   const promise: = self.getdeferred();    promise.resolve("ok");    return promise.promise; }

i'm using serverless 1.21.1, typescript 2.5.2, node 6.11.3 or 8.4.0 (2 different dev environments, both same result)

apparently, need run admin.app().delete();, otherwise connection firebase remains active, preventing process terminating.

so in example code, considering not need use firebase anymore after running function:

public getuser(uid: string): {   console.log('firebasemanager getuser method start');   const self: firebasemanager = this;   const promise: = self.getdeferred();    admin.auth().getuser(uid)   .then(function(userrecord: admin.auth.userrecord) {     console.log("successfully fetched user data:", userrecord);     admin.app().delete();     promise.resolve(userrecord);   })   .catch(function(error: firebaseerror) {     console.log("error fetching user data:", error.errorinfo);     admin.app().delete();     promise.reject('error getting firebase user ' + uid);   });    return promise.promise; }
