### Describe the bug
I have a schema like this:
```
type Baby
@model
@auth(rules: [
{allow: owner, ownerField: "caregivers", operations: [create, read, update, delete]}
]) {
id: ID!
caregivers: [String]!
...
}
```
When attempting to subscribe to updates to the model like this (android, kotlin):
```kotlin
Amplify.API.subscribe(
ModelSubscription.onUpdate(Baby::class.java),
/* onSubscriptionEstablished = */ { ... },
/* onNextResponse = */ {
if (it.errors.isNotEmpty()) {
Log.e("error response from baby update subscription", it.errors.toString())
} else {
...
}
},
/* onSubscriptionFailure = */ { ... },
/* onSubscriptionCompleted = */ { ... })
```
I get this response:
`[GraphQLResponse.Error{message='Validation error of type UnknownArgument: Unknown field argument caregivers @ 'onUpdateBaby'', locations='null', path='null', extensions='null'}]`
### Expected behavior
`Log.e` should never be called. And, it should wait to call `onNextResponse` until there is an actual update to the model.
### Reproduction steps
1. Create an API with the schema above.
2. Try to subscribe as above.

Contributor guide
Research direction
Start with the schema's repeated caregivers owner field and the Android Kotlin ModelSubscription.onUpdate(Baby::class.java) call, then trace the generated onUpdateBaby subscription arguments. Reproduce the validation error from the listed steps and verify that subscribing succeeds without an immediate error and that onNextResponse runs only for an actual model update.
