account.updatePushTarget gives AppwriteException document_already_exists
Hello guys,
I face again a problem with the account.updatePushTarget API. Now I am calling the updatePushTarget and I get the AppwriteException document_already_exists, not sure what the problem is and what the exception wants to tell me in this context. I am using the appwrite beta cloud and I make the call from my flutter mobile application my sdk version is appwrite: 13.0.0
This is my flutter code:
TypeScript
Future<void> setUserTarget(String? fcmToken, User user) async {
if (fcmToken == null || fcmToken.isEmpty) {
return;
}
try {
final existingPushTarget = user.targets
.where((target) => target.providerType == 'push')
.firstOrNull;
if (existingPushTarget == null) {
// Create new target
await _account.createPushTarget(
targetId: ID.unique(),
identifier: fcmToken,
providerId: PROVIDER_ID,
);
} else if (existingPushTarget.identifier != fcmToken) {
// Update existing target if token is different
await _account.updatePushTarget(
targetId: existingPushTarget.$id,
identifier: fcmToken,
);
}
} on AppwriteException catch (e, stackTrace) {
if (kDebugMode) {
print('Error setting user target: $e');
}
rethrow; // Rethrow to handle in calling code
}
}
And the response is attached in the screenshot.
Please let me know what the problem could be
Kind regards
TL;DR
Issue: Developer receives AppwriteException `document_already_exists` when using `account.updatePushTarget` API in Flutter mobile application.
Solution: The exception `document_already_exists` indicates that the document (push target) being updated already exists. To resolve this, ensure that for an existing push target, the `updatePushTarget` call is updating an existing record instead of creating a new one. Check the unique identifier being used and verify if the document needs to be updated or created based on the scenario.
