Creating a blog application using Next.js, Firebase Realtime Database, and Vercel for hosting has been seamless on my local machine. Even after running npm run build, everything functions perfectly. However, when deployed to Netlify in production, the snapshot.val() function in Firebase Realtime Database consistently returns a null value. Strangely, upon logging the snapshot object, I receive a comprehensive console.log with the DataSnapshot and its corresponding values.
Despite running flawlessly on my local setup, issues persist once deployed to Netlify's platform. The mysterious occurrence of a null return from the snapshot poses as a significant obstacle as it impedes essential data retrieval from the database.
DataSnapshot {
_node: ChildrenNode {
children_: SortedMap {
comparator_: [Function: NAME_COMPARATOR],
root_: LLRBEmptyNode {}
},
priorityNode_: null,
indexMap_: IndexMap { indexes_: [Object], indexSet_: [Object] },
lazyHash_: null
},
ref: ReferenceImpl {
_repo: Repo {
repoInfo_: [RepoInfo],
forceRestClient_: false,
authTokenProvider_: [FirebaseAuthTokenProvider],
appCheckProvider_: [AppCheckTokenProvider],
dataUpdateCount: 0,
statsListener_: null,
eventQueue_: [EventQueue],
nextWriteId_: 1,
interceptServerDataCallback_: null,
onDisconnect_: [Object],
transactionQueueTree_: [Tree],
persistentConnection_: [PersistentConnection],
key: 'https://blog-2ba4f-default-rtdb.firebaseio.com/',
stats_: [StatsCollection],
server_: [PersistentConnection],
statsReporter_: [StatsReporter],
infoData_: [SnapshotHolder],
infoSyncTree_: [SyncTree],
serverSyncTree_: [SyncTree]
},
_path: Path { pieces_: [Array], pieceNum_: 0 },
_queryParams: QueryParams {
limitSet_: false,
startSet_: false,
startNameSet_: false,
startAfterSet_: false,
endSet_: false,
endNameSet_: false,
endBeforeSet_: false,
limit_: 0,
viewFrom_: '',
indexStartValue_: null,
indexStartName_: '',
indexEndValue_: null,
indexEndName_: '',
index_: PriorityIndex {}
},
_orderByCalled: false
},
_index: PriorityIndex {}
}
This persisting issue demands urgent attention, as the functionality of the entire app heavily depends on the accuracy of database return values. Despite extensive research and attempts at resolution, I remain unable to resolve this frustrating setback.
Key points to note include:
The logged snapshot confirms that data is successfully fetched and accessible within the local environment.
No discernible errors or bugs exist within the code logic that may lead to such unexpected behavior.
Permissions have been appropriately configured, ruling out any access restrictions within the Firebase Realtime Database settings.
Your assistance in troubleshooting this perplexing issue would be greatly appreciated, as I have dedicated substantial time and effort to resolving this roadblock without success over the past two days.
