Xcode continuous error [FirebaseFirestore]: Committing transaction: <LevelDbTransaction Backfill Indexes: 0 changes (0 bytes):> – Ios swift

I have integrated Firebase 9.5.0 in my iOS project via Cocoapods.
I am using Xcode 13.4.1
I have following pods installed:

pod 'FirebaseCore', '~> 9.5.0'
pod 'FirebaseAuth', '~> 9.5.0'
pod 'FirebaseFirestore', '~> 9.5.0'
pod 'FirebaseStorage', '~> 9.5.0'
pod 'FirebaseFunctions', '~> 9.5.0'
pod 'FirebaseCrashlytics', '~> 9.5.0'
pod 'FirebaseAnalytics', '~> 9.5.0'
pod 'FirebaseMessaging', '~> 9.5.0'
pod 'FirebaseAppCheck', '~> 9.5.0'

In my AppDelegate.swift I am initialising Firebase as follows:

AppCheck.setAppCheckProviderFactory(providerFactory)
FirebaseApp.configure()
FirebaseConfiguration.shared.setLoggerLevel(.min)
Messaging.messaging().delegate = self
Analytics.setAnalyticsCollectionEnabled(true)

When I run the app on iPhone11 Simulator, I get following continuous print in Console logs every few milli-secs, non-stop:

[87345:733214] 9.5.0 – [FirebaseFirestore][I-FST000001] Committing transaction: <LevelDbTransaction Backfill Indexes: 0 changes (0 bytes):>

Which Transaction is it trying to commit? I have not invoked any Transaction yet. Why these never ending prints? Please help.
