Error loading staged page

**What Happened?**
I attempted to stage my project docs by navigating to: https://firebaseopensource.com/stageProject?org=anishkny&repo=integrify&branch=firebaseopensource

In response I got the staged docs URL: https://firebaseopensource.com/projects-staging/anishkny/integrify

When I load the second URL, empty page shows up with errors in console:

```

The timestampsInSnapshots setting now defaults to true and you no
longer need to explicitly set it. In a future release, the setting
will be removed entirely and so it is recommended that you remove it
from your firestore.settings() call now.
