Я отлично разворачивал функции, но потом они перестали работать, и я не знаю почему. Я вернулся к образцу кода (отсюда или здесь):
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
// Listens for new messages added to /messages/:pushId/original and creates an
// uppercase version of the message to /messages/:pushId/uppercase
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original')
.onWrite(event => {
// Grab the current value of what was written to the Realtime Database.
const original = event.data.val();
console.log('Uppercasing', event.params.pushId, original);
const uppercase = original.toUpperCase();
// You must return a Promise when performing asynchronous tasks inside a Functions such as
// writing to the Firebase Realtime Database.
// Setting an "uppercase" sibling in the Realtime Database returns a Promise.
return event.data.ref.parent.child('uppercase').set(uppercase);
});
Но теперь, когда я бегу firebase deploy --only functions, я получаю:
=== Deploying to 'mydb'...
i deploying functions

i runtimeconfig: ensuring necessary APIs are enabled...

Functions deploy had errors. To continue deploying other features (such as database), run:
firebase deploy --except functions
Error: Functions did not deploy properly.
Что случилось?
Консоль показывает те же сообщения об ошибках, без дополнительных пояснений:
