Hello guys,

The first check which version you’ve installed mine was 8.1.1 Please update firebase-tools by calling

sudo npm i -g firebase-tools

This will install latest version 8.4.1 And It fixed my issue. In fact, I have installed the latest firebase function and admin “firebase-admin”: “8.12.1”, “firebase-functions”: “3.6.1”,

I hope you’ve fixed the issue.
