Error with codegen and models preventing API sync

[ErnestDaDev]

When I use your example for many to many relationships in datastore with this schema

`type Post @model @auth(rules: [{allow: public}]) {
id: ID!
title: String!
rating: Int
status: PostStatus
editors: [PostEditor] @connection(keyName: "byPost", fields: ["id"])
}

type PostEditor @model(queries: null) @key(name: "byPost", fields: ["postID", "editorID"]) @key(name: "byEditor", fields: ["editorID", "postID"]) @auth(rules: [{allow: public}])
{
id: ID!
postID: ID!
editorID: ID!
post: Post! @connection(fields: ["postID"])
editor: AmpUser! @connection(fields: ["editorID"])
}`

API Sync fails and when I checked on the AWS Amplify data section, the table PostsEditor does not get created. and it shows it missing under post.

I am not sure what i am doing wrong.

Hi @BesavedTech, thanks for opening the issue.
I have a few questions for you to help me understand the error you encountered.

1. Were all models generated after via amplify codegen models after you edited schema.graphql, i.e. Did file PostEditor.dart correctly generated in your codebase?
2. By API sync, you mean push the backend via amplify push? What was the exact error message of the failure you saw?

@HuiSF yes it did and no I mean syncing in the app it self.

After making local changes to the GraphQL schema and data models, you would need to push the latest changes to AWS by running amplify push, as you mentioned "PostsEditor does not get created", it sounds like it's out of sync between AWS AppSync and your local changes.

You can check if you have local changes are pending to be pushed by running amplify CLI.
