Firebase Cloud函数-连接错误

Question

每当我调用云函数时，我都会在日志中获得Function execution took 5910 ms, finished with status: 'connection error'。我相信这与承诺和回报或!d.exists有关，但我还没能进一步缩小范围。

功能：

exports.useInvite = functions.https.onCall((data, context) => {
if (context.auth) {
throw new functions.https.HttpsError('failed-precondition', "cannot be authenticated");
}
if (!data.code) {
throw new functions.https.HttpsError('failed-precondition', "must provide an invite code");
}
console.log("Code: ", data.code);
return admin.firestore().collection("invites").doc(data.code).get().then(d => {
console.log("Exists: ", d.exists);
if (!d.exists) {
throw new functions.https.HttpsError('failed-precondition', "invalid invite code");
}
const added = new Date(d.data().created.seconds * 1000);
const week = 60 * 60 * 24 * 7 * 1000;
if ((new Date() - added) < week) {
return admin.firestore().collection("invites").doc(data.code).update({
validated: true
}).then(() => {
return null
}).catch(() => {
throw new functions.https.HttpsError('failed-precondition', "invalid invite code");
});
} else {
console.log("Expired!");
throw new functions.https.HttpsError('failed-precondition', "invite code expired");
}
}).catch(e => {
console.log(e);
throw new functions.https.HttpsError('failed-precondition', "invalid invite code");
});
});

以下更改应该可以完成任务：

exports.useInvite = functions.https.onCall((data, context) => {
class ExpiredCodeError extends Error {
constructor(message) {
super(message);
this.message = message;
this.type = 'ExpiredCodeError';
}
}
class InvalidCodeError extends Error {
constructor(message) {
super(message);
this.message = message;
this.type = 'InvalidCodeError';
}
}
if (context.auth) {
throw new functions.https.HttpsError('failed-precondition', "cannot be authenticated");
}
if (!data.code) {
throw new functions.https.HttpsError('failed-precondition', "must provide an invite code");
}
console.log("Code: ", data.code);
return admin.firestore().collection("invites").doc(data.code).get()
.then(d => {
console.log("Exists: ", d.exists);
if (!d.exists) {
throw new InvalidCodeError("invalid invite code");
}
const added = new Date(d.data().created.seconds * 1000);
const week = 60 * 60 * 24 * 7 * 1000;
if ((new Date() - added) < week) {
return admin.firestore().collection("invites").doc(data.code).update({
validated: true
})
} else {
console.log("Expired!");
throw new ExpiredCodeError("invite code expired");
}
})
.then(() => {
return { status: "OK" }
})
.catch(e => {
console.log(e);
if (e.type === 'ExpiredCodeError') {
throw new functions.https.HttpsError('precondition', e.message);
} else if (e.type === 'InvalidCodeError') {
//May be merged with the above clause...
throw new functions.https.HttpsError('precondition', e.message);
} else {
throw new functions.https.HttpsError('internal', e.message);
}
});
});
