"amplify push" creates new varaibles in type at AWS Appsync - React Native

Question

When I do amplify push , I get a few variables in the Appsync Schema.

This is from schema.graphql in react native amplify/backend folder.

type Botdata @model (subscriptions: null){
  client_id: String!
  id: String!
  lock_status: Float
}

And this is what I get on the Appsync Schema after amplify push

type Botdata {
   client_id: String!
   id: String!
   lock_status: Float
   createdAt: AWSDateTime!
   updatedAt: AWSDateTime!
   _version: Int!
   _deleted: Boolean
   _lastChangedAt: AWSTimestamp!
}

This causes my undefined type error for the entire operation. Please help me. Thanks!

Maybe you was turn on Optimistic Concurrency. This helpful when you have conflict data version between app and database but you need:

• Check _version when you use mutation if _version on app different _version field of row data on Database then operation mutation you return error.

If you don't need Optimistic Concurrency you can turn of that:

• go to folder project open command line with administrator.
• run: amplify update api
• choose: graphql
• choose: Disable conflict detection
• update api to cloud: amplify push Hope my answer helpful for you.
