Failed to Sync with Amplify Content

[Intelbis]

Description

I have successfully initiated amplify Auth ui and crud operations following the Amplify doc for Todo form.

Todo form saves inside the app locally and there are no errors in runtime but it ends with "Orchestrator transitioning from SYNC_VIA_API to LOCAL_ONLY" "Setting currentState to LOCAL_ONLY" "Stopped subscription processor." "No more active subscriptions. Closing web socket."

And the data is not synced to the cloud and it says Failed to sync

Hello @Intelbis - Have you made updates to your schema? If so, have you run amplify codegen models to generate new models and amplify push to push these schema updates?

[egyangel]

Same issue here :
I've already updated to 0.6.8 version and runing amplify codegen models and amplify push

My schema

 type User @model @auth(rules: [
    { allow: owner, ownerField:"id",identityClaim:"sub"},
    { allow: groups, groups: ["operator","administrator"], operations: [create, update, read, delete] }
]) {
    id: ID!
    cognitoId: ID!
    lastName: String
    phoneNumber: String!
    phoneNumberVerified: Boolean @default(value: "false")
    email: String!
    emailVerified: String @default(value: "false")
    name: String
    stripeId:String
    hasValidPaymentMethod: Boolean @default(value: "false")
    defaultPaymentMethod:String
    userStatus:UserStatus @default(value: "ACTIVE")
    balance:Float @default(value: "0")
    trip:[Trip] @hasMany
}

type Trip @model @auth(rules: [
    { allow: owner, operations: [read, update],ownerField: "userIdQuery",identityClaim:"sub"}
    { allow: groups, groups: ["operator","administrator"], operations: [create, update, read, delete] }
]) {
    id: ID!
    startTripDateTime: AWSDateTime
    endTripDateTime: AWSDateTime
    startBookDateTime: AWSDateTime
    endBookDateTime: AWSDateTime
    pauseInterval:[PauseInterval]
    totalBookedSeconds: Int
    totalTripSeconds:Int
    totalPauseSeconds:Int
    extraBookedSeconds: Int
    startLocationlon: String
    startLocationlat: String
    endLocationlon: String
    endLocationlat: String
    totalDistance: Float
    mPrice: Float
    totalDiscount: Float
    discountType: String
    vat: Float
    totalPrice: Float
    userIdQuery:String! @index(name: "byUserIdQuery", queryField: "tripByCustomerUserId")
    user:User @belongsTo
    vehicle:Vehicle  @belongsTo
    payed: Boolean
    paymentDate: AWSDateTime
    tripStatus: TripStatus
}

If I modify the trip from amplify studio i get this error:

GraphQLResponseException{message=Subscription error for Trip: [GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'AWSTimestamp' within parent 'User' (/onUpdateTrip/user/_lastChangedAt)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='_lastChangedAt'}]', extensions='null'}, GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'Int' within parent 'User' (/onUpdateTrip/user/_version)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='_version'}]', extensions='null'}, GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'ID' within parent 'User' (/onUpdateTrip/user/cognitoId)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='cognitoId'}]', extensions='null'}, GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'AWSDateTime' within parent 'User' (/onUpdateTrip/user/createdAt)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='createdAt'}]', extensions='null'}, GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'String' within parent 'User' (/onUpdateTrip/user/email)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='email'}]', extensions='null'}, GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'String' within parent 'User' (/onUpdateTrip/user/phoneNumber)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='phoneNumber'}]', extensions='null'}, GraphQLResponse.Error{message='Cannot return null for non-nullable type: 'AWSDateTime' within parent 'User' (/onUpdateTrip/user/updatedAt)', locations='null', path='[GraphQLPathSegment{value='onUpdateTrip'}, GraphQLPathSegment{value='user'}, GraphQLPathSegment{value='updatedAt'}]', extensions='null'}

@egyangel - If you are manipulating data in amplify studio, all records need to have the appropriate meta data fields (version, createdAt, updatedAt). It looks like lastUpdatedAt is null. I do not recall off the top of my head if studio will add these fields when adding a new record. You may need to add them manually. Do you mind opening a separate issue for this? It sounds like it could be a separate issue that we need to sync with the studio team on.

Hi Jordan, Yes i have run the sudo amplify codegen models & sudo amplify push commands prior to running the app. My model name has been renamed to Enquiries from Todos. Also I have wiped the data from the android emulator and ran the app again. Same issue..
I have uploaded the pictures of the console and cloud. Im not sure why it doesnt sync. Please let me know how to resolve this.
Thank you!

[Jordan-Nelson]

Can you share your schema?

[Intelbis]

Can you share your schema?

hi Jordan my schema.graphql is

type Enquiry @model @auth(rules: [{allow: owner}, {allow: public}, {allow: private}, {allow: private, provider: iam}]) {
id: ID!
description: String
isComplete: Boolean!
name: String!
noBedrooms: String!
}

many thanks!

Hi @Intelbis
I've already found another issue with my same problem.
Thanks

[Jordan-Nelson]

@Intelbis - The log indicates that there is a model with a null value for noBedrooms. Is there a model saved in dynamo that is missing this field? Can you see what data is saved via the AWS console?

Hi where to find this information? I just went to dynamoDB through aws console there’s nothing. Tables are empty. No tables found it says

[Jordan-Nelson]

If it is showing no tables, it may be displaying info for a different AWS region than where your app I located. You can select this in the top right of the console. Can you confirm you are viewing tables for the same region as your app?

Hi Jordan now I can see the tables. But where can I find the fields here.

[Jordan-Nelson]

If you click on the table name (I think you want to the third table in that list) there should be a button in the top right that says "Explore Table Items"

[Intelbis]

Hey Jordan I found these items in there. I can see bedRoom field here...

Hi Jordan after exporting those items and running project again seemed to resolve the conflict. It works now.

[Jordan-Nelson]

Okay great, I am glad you were able to resolve the issue. I will close this issue out.

For anyone facing this issue in the future, it looks like this may have been caused by the null fields after the schema was updated to make them non-null.
