[REQUIRED] Step 2: Describe your environment

- Firebase Component: _____ (Firestore)
- Component version: _____ "com.google.firebase:firebase-firestore:25.0.0"
[REQUIRED] Step 3: Describe the problem
I encountered an issue where a device was offline, and the permissions for a Firestore collection were changed. When the device reconnected and tried to upload data, I received a permission error:
2024-08-14 13:05:25.304 12838-12868 Firestore com...mple.triageflutterfireandroid W (25.0.0) [WriteStream]: (ce5a72e) Stream closed with status: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}.
2024-08-14 13:05:25.312 12838-12868 Firestore com...mple.triageflutterfireandroid W (25.0.0) [Firestore]: Write failed at test-collection/j320prNQkghLhwIf0z0j: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}
As a result, the data was never uploaded and got lost permanently.
Ideally, local data should never be removed unless explicitly instructed to do so.
Steps to reproduce:
Run
val firestore = Firebase.firestore
val settings = firestoreSettings {
setLocalCacheSettings(
persistentCacheSettings {
setSizeBytes(FirebaseFirestoreSettings.CACHE_SIZE_UNLIMITED)
}
)
}
firestore.firestoreSettings = settings
val collection = firestore.collection("test-collection")
firestore.disableNetwork().addOnCompleteListener {
val data = hashMapOf(
"0" to 0,
)
collection.add(data)
}
Change the Firestore rules to
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if false;
}
}
}
Wait a few moments for the new rules to take effect.
Run the previous code again but this time, without scoping the collection.add to firestore.disableNetwork().addOnCompleteListener. Also change the collection data to hashMapOf("1" to 0).
Your modified code should look like this:
val firestore = Firebase.firestore
val settings = firestoreSettings {
setLocalCacheSettings(
persistentCacheSettings {
setSizeBytes(FirebaseFirestoreSettings.CACHE_SIZE_UNLIMITED)
}
)
}
firestore.firestoreSettings = settings
val collection = firestore.collection("test-collection")
val data = hashMapOf(
"1" to 0,
)
collection.add(data)
You should get a permission denied error after running the above code.
Then change the rules to:
rules_version = '2';
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
and run the code again but change hashMapOf("1" to 0) -> hashMapOf("2" to 0)
The expect result would be three documents in the "test-collection" collection, with data {"0": 0}, {"1": 0} and {"2": 0}. But when following the above steps, only {"2": 0} actually exists.
