Cannot sync with the cloud

[otabek1]

Describe the bug
I am using Amplify DataStore and API to save to on the cloud. But I am getting "Failed to load class "org.slf4j.impl.StaticLoggerBinder" error when I try to save an object. I followed the same tutorials from the documentation and Youtube.
To Reproduce
Steps to reproduce the behavior:

1. Create data model and deploy.
2. Try to save it on the cloud with API

Expected behavior
A clear and concise description of what you expected to happen.

Platform
Amplify Flutter current supports iOS and Android. This issue is reproducible in (check all that apply):
[x] Android
[] iOS

My code: ``` @OverRide void initState() { super.initState(); firstNameController = TextEditingController(); lastNameController = TextEditingController();

_configureAmplify();

}

void _configureAmplify() async {
AmplifyDataStore datastorePlugin =
AmplifyDataStore(modelProvider: ModelProvider.instance);

final AmplifyAPI _apiPlugin = AmplifyAPI();

await Amplify.addPlugins(
    [datastorePlugin, _apiPlugin, AmplifyAuthCognito()]);

// Once Plugins are added, configure Amplify
// Note: Amplify can only be configured once.
try {
  await Amplify.configure(amplifyconfig);
} on AmplifyAlreadyConfiguredException {
  print(
      "Tried to reconfigure Amplify; this can occur when your app restarts on Android.");
}
print("configured");

}

void addAdult() async {
if (formKey.currentState!.validate()) {
print("validated");
try {
final item = Adult(
firstName: "Lorem ipsum dolor sit amet",
lastName: "Lorem ipsum dolor sit amet",
hasChildren: true,
totalEarned: 123.45,
totalTipped: 123.45,
phoneNumber: "(555) 123-6789");
await Amplify.DataStore.save(item).then((value) => print("done"));
} catch (e) {
print("Someting went wrong $e");
}
}
}

Hello @otabek1 , thanks for opening this issue.
To my knowledge, org.slf4j.impl.StaticLoggerBinder warning was thrown from System Logger not amplify libraries. And it doesn't block amplify cloud syncing.

Here are some tips to help you resolve the issue:

• Check the content of lib/amplifyconfiguration.dart if it has correct configuration
• Check App running log, do you see something similar to below item?

I/amplify:aws-datastore(11946): Orchestrator transitioning from LOCAL_ONLY to SYNC_VIA_API
I/amplify:aws-datastore(11946): Setting currentState to SYNC_VIA_API
I/amplify:aws-datastore(11946): Starting API synchronization mode.

• Check if you see any error message around Setting currentState to SYNC_VIA_API.
• Do you see any errors/exceptions after executing save operation?

Hey @HuiSF Thanks for the quick reply.

Here are my logs and there does not seem to be any issue:
I/amplify:aws-datastore(12408): Successfully enqueued PendingMutation{mutatedItem=SerializedModel{id='a6506aa0-a1b6-42f8-a30c-73ceeffe91b0', serializedData={firstName=Lorem ipsum dolor sit amet, lastName=Lorem ipsum dolor sit amet, totalEarned=123.45, phoneNumber=(555) 123-6789, hasChildren=true, totalTipped=123.45, id=a6506aa0-a1b6-42f8-a30c-73ceeffe91b0}, modelName=Adult}, mutationType=CREATE, mutationId=4756adb3-015a-11ec-a6a4-73a67a16df0d, predicate=MatchAllQueryPredicate}

But it is still not showing up in Admin UI

Successfully removed from mutations outboxPendingMutation

This message usually means the locally saved data has been synced to cloud successfully. Could you also check from the DynamoDB console, see if the data has been written into the tables?

[otabek1]

I checked it is empty.

This is a bug report I just filed that includes a couple of bugs I found and the workarounds to each
after reading your bug report I think it could help
#822

[HuiSF]

@otabek1 could you please paste the schema of the model that cannot be synced to cloud? (you can find the schema in amplify/backend/api/<your api name>/schema.graphql).

[HuiSF]

Hi @otabek1 I wanted to follow up about this issue.

We have two know issues may prevent model data to be synced to cloud.

Could you please take a look at the description see if any of them happen to match your use case?

1. Issue 1
2. Issue 2

I'm having this EXACT same issue and I cannot find when or how it stopped working.

type Configuration @model @auth(rules: [{allow: private}, {allow: private, provider: iam}]) {
id: ID!
var1: String
var2: String!
var3: String
var4: String
var5: String
var6: String
var7: String
}

Result after save:

But it simply will not show in DynamoDB or Admin UI.

@otabek1 are you using a specific version of okhttp in your android library?

If yes, update to the latest will resolve the issue.
