Amplify.Hub.listen never get "ready"

[harrynguyenangle]

Description

Currently I have upgrade Amplify Gen 1 Flutter v1 Libaries from pubspec.yaml amplify_flutter: ^1.8.0 amplify_auth_cognito: ^1.8.0 amplify_datastore: ^1.8.0 amplify_api: ^1.8.0 amplify_storage_s3: ^1.8.0 amplify_analytics_pinpoint: ^1.8.0

My codes worked before, everytime app opens, it can trigger 'ready' and network is up, data is all sync to cloud Now, after changing some schema, remove schema model (by command amplify push --allow-destructive-graphql-schema-updates) And upgrade Amplify CLI the latest version, -> run the app, print (hubeventname) It never gets "ready", it just got "syncQueriesStarted" so far Then I test with Amplify.Datastore.save, it does not upload to Database

@harrynguyen2510 thanks for taking the time to raise this issue. While we investigate could you please provide answers to the following questions:

• did you run amplify codegen models after schema update?
• do you get any error message when calling Amplify.Datastore.save, if so can you please share the logs?
• dose Amplify.Datastore.save saves the data locally on the device?

[harrynguyenangle]

• yes I did, even to make sure, I delete Models folder and run command amplify codegen models
• yes it saves normally and the subscription catches new data locally, but it does not sync to cloud

@harrynguyen2510 thanks for providing these info. Is this issue exclusive to iOS, or does it also happen in Android? could you please provide both the original and updated schemas?

[harrynguyenangle]

I didn't test on Android, but I tested on 3 iOS devices, and it happened the same bug.

Here is current Schema type User @model @auth(rules: [{allow: public}]) { id: ID! authenticateID: String! username: String! fullname: String! email: String! phonenumber: String password: String profilepicKey: String bio: String resign: Boolean isDeveloperPermit: Boolean isActive: Boolean updateUserType: String oneSignalID: [String] updateOneSignalIDType: String platform: String deviceToken: [String] updateDeviceTokenType: String userPermission: [String] updateUserPermissionType: String authority: [String] updateAuthorityType: String followingUserids: [String] updateFollowingType: String followedbyUserids: [String] updateFollowedbyType: String createdAt: AWSDateTime updatedAt: AWSDateTime }

This is a schema I removed currently (did remove others some before, but worked normally)

type MediaFileRatio @model @auth(rules: [{allow: public}]) { id: ID! filekey: String! ratio: Float! }
I deleted all data on this model, then delete on schema.graphql, amplify codegen models, amplify push, then deploy on studio

Another question that I see some amplify flutter plugins are 2.0.0. Are these for Gen 2 or just upgrade version for Gen 1? Thanks

@harrynguyen2510 thank you for providing these details. we will look into this issue and get back to you with any updates.

re: Another question that I see some amplify flutter plugins are 2.0.0. Are these for Gen 2 or just upgrade version for Gen 1?

The latest version of the Amplify Flutter library is 2.0.0, which currently supports Gen1 configurations through amplifyconfiguration.dart. you can use either Amplify Gen1 or Gen2 to setup your backend. With Amplify Gen2, you must use the --outputs-version 0 flag with ampx command. Development for supporting Gen2 with --outputs-version 1 is in progress, you can follow #4834 for update.

The cause of issue is that I mistakely change attribute name of schema model while the model on cloud, on that attribute, currently having values. So it was error for sync Resolved by deleting these data of schema model in DynamoDB, then it works normally
