Error: Functions did not deploy properly - firebase

Question

Functions deploy had errors. To continue deploying other features (such as database), run:
firebase deploy --except functions
Error:
Functions did not deploy properly.

Answer 1

Try running deploy with --debug. For example: firebase --debug deploy.
In my case the function looked like this:
exports.test = functions.firestore.document('chats').onCreate((snap, context) => {
...
});
The debug log contained the following error message:
fieldViolations=[field=event_trigger, description=Expected value chats to match regular expression [^/]+/[^/]+(/[^/]+/[^/]+)*]]
And that's when I realized that chats is not a document but a collection. I changed the path to that of the collection and everything worked fine.
EDIT:
To view more logs you can also try:
firebase functions:log
or
firebase functions:log --only <FUNCTION_NAME>
Link to documentation.

Answer 2

I had the same issue with Firestore ,my problem was that the path to the document was bad. I had a slash at the beginning and the end of the path to my document like I used to do with Firebase Realtime Database path.
Hope it helps someone.

Answer 3

Just close whatever IDE you're using and then reopen it. Then on node redeploy your functions. This should resolve the issue.

Answer 4

I got this error as well, I had the problem that a dependency was missing in the package.json file.
By running
firebase --debug deploy it returned an error on the user code.
firebase functions:log gave then the specifics, that a package was not included.

Answer 5

I deleted yarn.lock then error goes away. I think package-lock.json and yarn.lock should not exist together.

Answer 6

Check your json modules dependencies inside functions folder.
There's an specific json package there.
If some module you are including in the project and is not there (in json) you probably will have the error mentioned.
To install just run:
npm install <module> --save
or
yarn add <module> --save
and then run your deploy again:
firebase deploy --only functions

Answer 7

In my case firebase deploy failed with the error "Error: Functions did not deploy properly." and no further explanation. I noticed that no functions could be deployed even the ones I didn't touch.
So I checked for dependencies and I found that a library was not present in the "package.json".
So I execute this command:
cd functions && rm -rf node_modules && rm package-lock.json && npm install && npm install [specific Librairy not in package.json] && firebase deploy
After that the deployment succeeded and the missing dependency appeared in the package.json

Answer 8

Recently Firebase lets you use Functions only if you have the Blaze-Pay as you go plan. So you cannot deploy functions as well, and you will get this same error message without any further clarifications.

Answer 9

Mine was about;
"Function deployment failed because the billing account is not available."
So I had pending payment, after paying, it worked as expected.

Answer 10

I was running into the same generic error message, and ended up running (as mentioned in this question):
firebase --debug deploy --only functions:[functionName]
This revealed the actual issue (my project did not have a default GCP resource location, fix for this described here: Firebase Project Initialization Error: Cloud resource location is not set for this project)
Once I set the GCP resource location, function deployed without issue!

Answer 11

In my case, After a long time of searching, I found the reason to be that I had disabled billing for the project for debugging.
It worked fine now after I enabled it in the Google cloud console.
It's really sad how firebase can't show any useful error message to suggest the problem. I found this after many trials.

Answer 12

I faced a similar problem, but I was using Typescript.
It was basically targeting a non-supported javascript version (ES2020). I changed the tsconfig.json and it deployed normally
"lib": [
"es2019",
"es2020.bigint",
"es2020.string",
"es2020.symbol.wellknown"
],
"module": "commonjs",
"target": "es2019"

Answer 13

After getting the above deploy error, I edited the index.js file and changed the name of the function from "helloWorld" to "heyWorld" and suddenly the firebase deploy command worked.

Answer 14

If anyone gets here trying to deploy ssr functions in angular universal with firebase, it is because firebase is not included in your functions.
1.) cd functions
2.) npm i firebase#latest
3.) npm run deploy
4.) cd ..
5.) now when you run ng deploy it should work correctly... The key here is to add firebase, and deploy with npm run deploy first...

Answer 15

try to add this
"runtime": "nodejs12"
in your firebase,json
example :
"functions": {
"source": ".",
"ignore": [
".firebase/**",
"**/node_modules/**",
"**/public/**",
".firebaserc",
"firebase.json",
"postcss.config.js",
"README.md",
"tailwind.config.js"
],
"runtime": "nodejs12"
}

Answer 16

was with the same error, I ended up solving it by updating package.json
from:
"engines": {
"node": "12"
},
to:
"engines": {
"node": "14"
},

Answer 17

$ in path causes Error: Functions did not deploy properly.
before:
`export const newMessage = functions.firestore.document('chats/${chatId}/messages/${messageId}').onCreate(handleNewMessage())`
after:
`export const newMessage = functions.firestore.document('chats/{chatId}/messages/{messageId}').onCreate(handleNewMessage())`

Answer 18

In my case, the location for the Firestore was not correctly set. From the Functions Documentation:
By default, functions run in the us-central1 region.
In my case, Firestore was set up on a different location. You can find this under Project Settings, at Default GCP resource location.
To fix it, simply make the following change:
// Before
functions.firestore.document("...").onCreate(...)
// After
functions.region("asia-east2").firestore.document("...").onCreate(...)

Answer 19

Follow the steps below:
Deploy with debug enabled:
firebase --debug deploy
You will see the error printed in your console.
In most cases it is something similar to the line below:
npm install before continuing.\nnpm ERR! \nnpm ERR! \nnpm ERR! Invalid: lock file's body-parser#1.19.0 does not satisfy body-parser#~1.0.1\nnpm ERR!
If the error is similar to "lock file's body-parse" in 1) above:
Go to the views directory in your project and edit the dependencies section in your package.json file as below:
Change the body-parser version to the latest version shown in the error printed in 1) above. In my case it was from body-parser#~1.0.1 to body-parser#~1.19.0
Run: npm install
Re-deploy with: firebase deploy
This should work.
If you get a 403 error from your hosting URL after re-deploying, your CLI version could be out of date:
Login to you google cloud account and go your the google cloud console.
Delete your Cloud Functions
Update Firebase CLI using: npm install -g firebase-tools
Re-deploy: firebase deploy

Answer 20

My firebase couldnt find the modules firebase-functions and firebase-admin on deploy because I wrote them in devDependencies instead of just dependencies. But after it ... I still had an issue. But this solved it for me: https://github.com/nuxt/nuxt.js/issues/2714#issuecomment-423048343.
Just notice node 8 as engine object in your function's folder package.json and add the babel snippet in your nuxt config.

Answer 21

I had same problem with Firebase project deployment. Then figure out error and find that some module paths are cause problem. Then i changed the path of that module.
To try redeploying those functions, run:
firebase deploy --only functions:api,functions:createScream
To continue deploying other features (such as database), run:
firebase deploy --except functions
Error: Functions did not deploy properly.
The error shows that could not find modules.
Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module (../key/your secret key.json) '
Then i changed the path of my secret key that is required for login credentials and put it in different folder. Then run firebase deploy.
That work for me.

Answer 22

I had the same problem. The problem came from the fact that I had an index.js file and package.json file in the root folder and, after running the firebase functions init command, also an index.js and package.json in the functions folder. The dependencies are only listed in the package.json file in the root folder, not in the functions folder. I copied the dependencies to the package.json file in the functions folders and everything worked like a charm.

Answer 23

Deleting the build functions folder worked to me

Answer 24

firebase functions:log
This allowed me to find out the problem in my case: one of the packages was not listed among the dependencies in package.json

Answer 25

This worked for me today: Delete Function and Redeploy.

Answer 26

It happened the same to me but unfortunately I had not any error with --debug.
I then deleted all my deployed functions in the firebase console and
cd functions
rm -rf node_modules
npm install
firebase deploy --only functions
and it worked like magic.

Answer 27

I got the same error
Functions were working in emulator, but couldn't be deployed.
When I deployed functions using debug, I got no more specific info.
Then I found out, that my IDE accidentally imported lib (that I wasn't even using) from parent folder where is my Svelte project located.
Removing that import fixed my error, obviously.

Answer 28

I deleted the recently added 3rd party library (from package/package-lock.json as well). And checked the name of the function to not be a duplicate.
This worked for me.

Answer 29

If u are using SSR you need declare your node version In my case my node version is 14 and firebase was deploying with 10.0 I set this config on angular.json
"functionsNodeVersion": 14
"serve-ssr": {
"builder": "#nguniversal/builders:ssr-dev-server",
"options": {
"browserTarget": "Rioja-web:build",
"serverTarget": "Rioja-web:server"
},
"configurations": {
"production": {
"browserTarget": "Rioja-web:build:production",
"serverTarget": "Rioja-web:server:production"
}
}
},
"prerender": {
"builder": "#nguniversal/builders:prerender",
"options": {
"browserTarget": "Rioja-web:build:production",
"serverTarget": "Rioja-web:server:production",
"routes": [
"/"
]
},
"configurations": {
"production": {}
}
},
"deploy": {
"builder": "#angular/fire:deploy",
"options": {
"ssr": true,
"functionsNodeVersion": 14
}
}
}

I had the same problem.
updating node engine to 16 in package.json solved the issue.
My nodejs local version was 16.
{
...
"engines": {
"node": "16"
},
"main": "lib/index.js",
"dependencies": { ... }
}
