Upload base64 image to Firebase Cloud Storage using firebase-admin in nodejs

[Code Mickey]

I have a function in nodejs backend where I wish to upload images (base64 images) to my google cloud storage using firebase-admin package. I followed the documentation on adding a service account key to allow access and upload to the storage but I get an error whenever I try. I used the file.save() method but no success with error "Invalid response body while trying to fetch https://www.googleapis.com/oauth2/v4/token: read ECONNRESET". I need help. Thanks in advance
