I was able to reproduce this failure by deploying firebase functions from my local environment using Firebase CLI. Looking up the "failed to get status of all the deployments" error online, all I could find had to do with temporary outages. Since there is a large number of functions, I guessed maybe it has something to do with quota or similar even though that is not the error? So, I went ahead and tried to deploy the functions one by one and deployment was successful for all functions.
Assuming deploying functions one at a time will work through CircleCI as well, a few possible solutions:
(1) Change the firebase deployment in Circle CI to be one function at a time --> deploying each function adds to the total run time
(2) Detect if there were any changes in the "functions" folder and only then kick the deployment to firebase.
(3) Manually deploy a specific function when making changes to it

Submitted pull request for branch update_firebase_deployment_in_ci_241 with a temporary fix (option (1) described above).
Broke the command to deploy firebase functions to multiple deploy commands, one for each function.
The failure described in the bug reproduces when deploying using Firebase CLI in my local environment. Deploying one function at a time succeeded.
Will only be able to test this once the change is merged and a new build kicks in
