firebase-tools: Firebase deploy stuck at "cleaning up build files..."

firebase logout and then login fixed it for me.

Goodness. This issue sat in my inbox for an inexcusable amount of time. Sorry; I don’t get to code much these days and didn’t check GitHub for a few weeks. The code to deploy your functions has been completely rewritten between those two versions. Some changes intended to improve reliability and some also intended to help performance.

Can you file a support ticket at https://firebase.google.com/support to make sure you get the attention you deserve? A firebase-debug.log would let us see pretty quickly where the failures are and help us fix whatever regression is hitting you.

It shouldn’t be getting stuck, though it’s not fatal if you ctrl + c to kill that part of the process; it happens after your functions are already done deploying. Out of curiosity, let’s try absolutely cleaning your artifacts and seeing if you continue to get stuck afterwards. Try running the following commands:

# Get the latest version of the firebase command
npm install -g firebase-tools

# Unlock the deletegcfartifacts command
firebase --open-sesame deletegcfartifacts

# Run a full purge of your GCF artifacts directories
firebase functions:deletegcfartifacts

This process will check your per-metro Google Container Repository buckets for the gcf folder and recursively delete its contents. If you’ve been putting your own images in that directory they will be deleted by this command as well. Can you run this command to completion and then write back in a week or so whether you continue to see deploys get stuck?
