Unexpected Error while deploying using "firebase deploy --only functions" in firebase-tools@11.8.0 (latest version) (Could not find functions.yaml. Must use http discovery).

[REQUIRED] Environment info

firebase-tools: 11.8.0 (latest release)

Platform: : macOS

[REQUIRED] Test case

If I make a function on the index.js file, and then I try to deploy using: firebase deploy --only functions:nameOfYourFunction I get an Unexpected Error at the end.

[REQUIRED] Steps to reproduce

Using npm or whatever package manager you prefer, run these on your terminal,

npm install -g firebase-tools firebase login firebase init functions

Now under the functions folder, make sure you have installed node modules using npm install, and finally you create a basic function you like on index.js after you are done importing stuffs, for example:

const functions = require(‘firebase-functions’); const admin = require(‘firebase-admin’); admin.initializeApp();

exports.yourFunctionName = functions.https.onRequest(async(req,res)=>{ functions.logger.log(res.body); //just for an example. })

Now when you try to do:

firebase deploy --only functions:yourFunctionName

You’ll see this error message in the end:

[debug] [2022-09-05T11:21:09.063Z] Serving at port 9005

[REQUIRED] Expected behavior

Expected behaviour is that the function gets deployed successfully without any error.

[REQUIRED] Actual behavior

Actual behaviour is that function normally get’s deployed successfully and just after this update, this issue came into play.

I have the same problem with my Nuxt app. To avoid it, I delete the node_models folder in the output directory and reinstall it.

$ NITRO_PRESET=firebase npm run build && cd .output/server && rm -rf node_modules && npm i && cd ../../ && firebase login && firebase deploy

After that everything works normally.

Node v16.18.1 Firebase v11.16.1 Ubuntu 22.04

I could fix this issue just by downgrading the version of firebase tools to v10.0.0 using: npm install -g firebase-tools@10.0.0
