## The problem
Issue GetStream/stream-chat-js#1725 (closed, 9 comments): The "Authenticate with Stream Chat" Firebase Extension fails to install with a Node.js 18 deprecation error. Google Cloud has decommissioned Node.js 18 runtime and no longer allows deployments using it.

**Error Details**
Runtime nodejs18 is decommissioned and no longer allowed. 
Please use the latest Node.js runtime for Cloud Functions.
The following Cloud Functions fail to deploy:

ext-auth-chat-revokeStreamUserToken
ext-auth-chat-getStreamUserToken
ext-auth-chat-deleteStreamUser
ext-auth-chat-createStreamUser

**Extension Information**

Extension Name: Authenticate with Stream...

## What fixed it
The 'Authenticate with Stream Chat' Firebase Extension failing with 'Runtime nodejs18 is decommissioned' was fixed by Stream: they submitted updated extension versions, Firebase accepted them, and a user confirmed the latest version installs fine. If the extension won't install on a decommissioned runtime, update to the newest extension version rather than pinning the old one.
