Blocking: `firebase-tools` Complains About Latest Version of `firebase-functions`

[Swivelgames]

After yesterday's deployment tools that broke engines that didn't satisfy "~0.10.12", I updated all versions of firebase-* related packages (global and local). I'm no longer able to use the tools:

@Swivelgames Do you have a Firestore function? And are you able to deploy your project properly still?

[Swivelgames]

@laurenzlong Firestore? Negative. Just firebase function, which is the project I'm working in right now that doesn't seem to be working anymore.

Please note that each attempt is being done on a known working revision that was fully functional prior to the updates published yesterday.

@Swivelgames Can you try deploying with the new dependencies, it'll probably fail but print a more clear error message than what the local emulator will print.

[Swivelgames]

@laurenzlong Apologies, I wasn't specific. The deployment was successful with the latest versions. The local firebase serve, however, does not.

[laurenzlong]

No worries! Thanks for clarifying. I created a branch that has better error logging. Can you install it by running:

npm install -g https://github.com/firebase/firebase-tools.git#ll-printparsererr

Then run the local emulation again and let me know what the log looks like.

Caching Issue?

I guess I'll chalk this up to some sort of caching on some end. After attempting to install your ll-printparsererr branch, it "magically" started work. However, if you remember, I posted about 45 minutes ago the same steps which still resulted in the errors.

And it's a success all of a sudden? w4t.

Thanks for your magical touch, @laurenzlong ! 🤣

Recommendation To Others

In the future, I'll probably run the following:

$ npm cache clean
$ yarn cache clean

I'm not sure if this was the real issue or why, but it all seems to be working now.

[laurenzlong]

Thanks for the update! Glad it works now :)
