Swift 5/iOS 13+ – Google Cloud Functions won't let me add a value - swift

Question

I'm using Google Cloud Functions (GCF) to schedule posts on Instagram (an app similar to Hootsuite). I just integrated local notifications and I want to add the ID (generated automatically by my "notificationManager") to the post (data sent to Google Cloud).
Basically, the way that it works is the app sends the data to GCF and GCF is responsible for adding the elements to Firestore Database, but after many failed attempts, I cannot seem to figure out how to add an additional value. My goal is to add the element "notificationIdentifier", but for some reason, GCF won't register it (I can't even see it in the logs!).
Here's what's in GCF:

success(JSON(response))
}, failure: { (error) in
let err = JSON(error)
print(err)
failure(err)
})
}
I did check and see if "param" included "notificationIdentifier" when sending to GCF and it does, but if I check the logs in GCF, I can see everything that's supposed to be except for "notificationIdentifier". And when I replace, for example, "tags" with the "notificationIdentifier", then it works.
I'm unsure if Firestore/Firebase has a limit of elements or not and why this behaviour is happening. To be honest, I couldn't find much information online.
Feel free to ask any questions if I was unclear, as I tend to be!

Answer 1

This was solved quite simply, the app is using a Cloud Function called "API" which is used before accessing the "Schedule" function. So changed the values (or rather added the values) and everything is working fine now.
