Experiencing the exact same issue. All was well day before yesterday. Thanks for posting this - I've been racking my brains trying to figure out what I've done wrong that would have broken my little project. Tried reverting to version 7.0.0 of firebase-tools but still got the same error. firebase deploy seems to work fine; it's firebase serve that gives the error.

I've opened a PR to fix it, see #1482.

I'm also running into this issue.

Literally having the same issue. Tried just running the hello world program and gives the same error if using firebase serve. Good to know I'm not the only one.

Thanks all for reporting and @merlinnot for the fix! That's what we get for relying on internal APIs

anyone else getting an unexpected error, when trying to run firebase serve with the hello world program?

Yes @mmillerscsu . First got this error last night. Was working on an existing project, so my first thought was: I screwed up something. A few hours later, I decided to create a project from scratch and that's when I noticed that even the helloWorld function on a brand new project gives the same errror on trying to run firebase serve. Then this morning I saw this thread.

If you are experiencing this issue, the workaround is to run npm install [email protected] in your functions directory.

Thanks @samtstern Any ETA on when this will be fixed though?

1482 is already underway, this should be fixed by the end of the day.

If anyone needs a quick fix for this issue, I just tried workaround suggested by @samtstern and firebase serve now works fine. Thanks again @samtstern

@samtstern got it to work thanks! I will be using this temporarily until they update the fix.

@lcarbonaro did you run firebase init first, and then firebase-functions?

@mmillerscsu No I just ran npm install [email protected] in the functions folder as @samtstern suggested.

@lcarbonaro got it to work now thanks.

Thanks @samtstern for the workaround, that helped me.

I tried installing 3.0.2 & firebase/firebase-functions#master (per the ref'd merged PR), and still getting that error in both cases. Maybe another dep in the mix causing issues? I'm:

"actions-on-google": "^2.8.0",
"firebase-admin": "^8.2.0",
"firebase-functions": "3.0.2",
"firebase-functions-test": "^0.1.6",

@lefnire Same error message? I have the same dependencies on my functions package.json but the only error that I got it was from grpc that made me update the node version to 10.

@jheredia scratch that, I nuked node_modules & functions/node_modules tried again, all good

Delete node_modules then run npm install, npm install firebase-admin and npm install [email protected]

npm install [email protected] (not 3.0.2) worked for me

This has been fixed in firebase-tools 7.1.0

no it hasnt been fixed

Fixed it for me when i run npm install [email protected] inside functions as described in this stackoverflow answer

npm install [email protected] fixed it for me

Use node ver 8 fixed for me ;)

Still not fixed on my side

node -v
v10.15.0

back to

npm install [email protected]

This appears to be working for me in [email protected]

got the same issue. @samtstern Is there any chance to see it fixed soon?

@hyzhak this should be fixed in the latest release of firebase-tools. If you're having issues still, can you open a new issue with the appropriate information so we can better track it? thanks.

For those running WSL 1 (linux on Windows 10), using firebase tools 7.10 or 7.2.2 to fix this issue might still be a problem, due to something in 7.10 causing a problem for WSL users: #1458.

I run WSL 1 with firebase tools 7.0.2, node 10, and installing [email protected] fixed this problem for me.

For me it was because firebase-tools was installed globally after upgrading to latest.

npm uninstall -g firebase-tools

then update your scripts to to use npx equivalent commands.

npx -p firebase-tools serve

Still with the same problemn, solved with [email protected]

Worked with me:

• delete the folder "node_modules" inside the "functions" folder
• npm install the "firebase-functions" more recent (actually 3.6.0)
• uncomment the code inside the "functions/src/index.ts"
• try close and open the command line

here is what worked for me yesterday

1. npm i firebase-functions@latest
2. npm i -g firebase-tools@latest
3. close and open the command line

Fixed in 4.15.1
