In the step: amplify api update

No AppSync resource to update. Use the "amplify add api" command to update your existing AppSync API.
The "path" argument must be of type string. Received type undefined

Looks like we have to amplify add api first

hi guys, I have an issue when running

amplify api update

and running the shell script after building, it basically updates AWS cognito with the User schema inserted in schema.graphql, but after the build the schema.graphql schema reverts back to this

type Task @model {
id: ID!
title: String!
description: String
status: String
}
type Note @model {
 id: ID!
content: String!
}

The build output shows it did run the script I added as per the tutorial

this shows it did this process twice, uploading the USe graphQL schema I entered, but then went back and downloaded from the cloud the Task and Note schema, , and it did an overwrite in the xcode project after this on the schema.graphql .

Any idea whats going on?

Got an error : Cannot find type : ‘User’ in scope. Is it part of a library or Framework ? I haven’t found it in the code and in Combine.
