Firebase admin sdk not working on Apple m1 processor

[Don Morris]

I am getting a google auth error when trying to use the firebase admin sdk to read a firestore collection. The same code works fine on my intel mac.

I'm using node v15.4.0 built for arm64 on a macbook air m1.

Here is the error message

/Users/don/.nvm/versions/node/v15.4.0/bin/node /Users/don/Dropbox/Business/PicSaver/code/cloudfunctions/functions/lib/server.js uploads

Error: Could not load the default credentials. Browse to https://cloud.google.com/docs/authentication/getting-started for more information.

Hi Don,

For bugs in the Admin SDK the best place to report them is on GitHub:

https://github.com/firebase/firebase-admin-node

From the looks of your error stack this bug likely is not related to the M1 processor architecture.  It looks like your computer does not have gcloud credentials.  This is a common thing to forget when getting a new computer, So you have a few options:

1. If you want to authorize as yourself (end user credentials) install the "gcloud" command line tool and run "gcloud auth application-default login"
2. If you want to authorize as a service account set the "GOOGLE_APPLICATION_CREDENTIALS" environment variable to the path to a service account JSON key. More information on that approach is here: https://firebase.google.com/docs/admin/setup#initialize-sdk

That fixed the auth issue on my mac.

I'm a bit puzzled though because I didn't do this on my linux server that run the same code with no problems. I have run this code on several ubuntu servers without installing gcloud or logging into my gcloud account.

Hmmm well those servers have a credential somehow!  If your server is running on Compute Engine, Cloud Functions or another similar trusted Google Cloud environment then the Admin SDK is able to discover the credentials using the private Compute Metadata API.

They are running on amazon lightsail.

I'll do some research.

Been a bumpy road trying to get the Mac with m1 chip working correctly for software development.
