Running the provided https function example locally does not work about firebase-functions

@ubaidazad I came here looking for a solution to the same problem. Switching to node v6.11.5 fixed it for me. Might be worth a shot.

EDIT: @laurenzlong So this error occurs when there is some JS error in the bundle code. in my case I was using firebase UI and was generating the error "window not found" since firebaseUI does not support SSR. I think it will be great if the emulator can give the actual stack trace so we know! :)

unfortunately this still happens. this is the error log
⚠ functions: Failed to load functions source code. Ensure that you have the latest SDK by running npm i --save firebase-functions inside the functions directory. ⚠ functions: Error from emulator.

hey @janrop thanks for reporting, 3.10.10 is not an actual firebase-tools version (see https://github.com/firebase/firebase-tools/releases). Can you run "firebase --version" and update the issue with what it prints out?

[janrop]

Hey @laurenzlong. Sorry that was what npm gave me.
"firebase --version" is 3.9.1

[laurenzlong]

hey @janrop I'm unable to reproduce this. Can you try updating your firebase-tools by running:

npm install -g firebase-tools

There is now a new release of firebase-tools (v.3.9.2) that requires a higher version of google-cloud/functions-emulator, which has some bug fixes.

Please reopen the issue if that doesn't fix it.

[laurenzlong]

This is the same issue as firebase/firebase-tools#482, which I will work on fixing. You can follow the progress there.

still getting the same error in latest firebase-tools

Shutting down...

 node -> v6.11.0
 npm -> 3.10.10
 firebase -> 3.16.0

The node v6.11.5 works for me!
