Describe the bug

Hi,

I just started experimenting with AWS Amplify and I'm struggling with an error about authorizing an update in DynamoDB.

Expected behavior

I was expecting a successful update.

Reproduction steps

So, my defined backend looks like this:

const schema = a.schema({
  Users: a
    .model({
      userId: a.string().required(),
      email: a.email().required(),
      name: a.string().required().default(''),
      hasSubscription: a.boolean().required().default(false),
      hasFinishedOnboarding: a.boolean().required().default(false),
      signInMethod: a.string().required().default('anonymous'),
    })
    .identifier(['userId'])
    .authorization(allow => [allow.owner()]),
});

export type Schema = ClientSchema<typeof schema>;

export const data = defineData({
  schema,
  authorizationModes: {
    defaultAuthorizationMode: 'userPool',
  },
});

Regarding auth, I configured only sign in with Google, which works and I am able to create a user object in DynamoDB. As a second step I was trying to update a field in the object using:

try {
      const client = generateClient<Schema>();
      const updatedUser: User = { ...user, name: newName };
      const { data, errors: updateErrors } = await client.models.Users.update(updatedUser);
} catch (error) {
      console.log(error)
}

The user object has all the fields according to the schema + the owner field, as specified in the documentation as well. When calling the above I catch the error: TypeError: Cannot read property 'isReadOnly' of undefined]

I started debugging and found the issue. Inside APIClient.ts there is this code:

    case 'UPDATE':
      // readonly fields are not  updated
      variables = {
        input: arg
          ? Object.fromEntries(
              Object.entries(
                normalizeMutationInput(
                  arg,
                  modelDefinition,
                  modelIntrospection,
                ),
              ).filter(([fieldName]) => {
                const { isReadOnly } = fields[fieldName];

                return !isReadOnly;
              }),
            )
          : {},
      };
      break;

It seems the issue is that the arg object has all the fields from the schema + the owner field, but the fields object has only the fields from the schema. So when the filter function is called for each element, it reaches the point where it tries to access fields.owner.isReadOnly, where fields.owner is undefined because owner is not part of the schema.

So, am I doing something wrong? Have I missed something in the documentation or is it an issue?

If you need more details, let me know.
