Functions deploy had errors. To continue deploying other features (such as database), run:
    firebase deploy --except functions

Error: Functions did not deploy properly.

Expected behavior

Function should be deployed. I have been using this project for last 3 months. I started getting this error recently. I don't remember making any changes that would have broken the deployment.

Actual behavior

Error: Cannot find module 'firebase-functions'

What was wrong @technohowl ? I'm having the same issue.

[mdo5004]

My issue resolved itself on its own, it seems. I deployed, had the error, waited an hour, deployed again, and had no issues. Which, in itself, may be a big issue.

@mdo5004 There was a production incident earlier that was causing this error, but things should be back to normal now! https://status.firebase.google.com/incident/Functions/17027

If anyone experiences something similar in the future (where the error is during execution, not deployment), please open a support ticket at https://firebase.google.com/support/contact/bugs-features/ so it can be triaged properly.
