### Describe the bug

When selecting an item containing an array of a custom type via the Amplify data manager interface, the interface crashes. Displaying "Something went wrong. Please try again later."

Browser console output displays:

TypeError: Cannot read properties of undefined (reading 'call')
at za (chunk.8720.js:1:256968)
...
at E (remoteEntry.js:77:1364)

### Reproduction steps

1. Define a custom type & model utilizing custom type:

```js
Type1: a.customType({
field1: a.string(),
}),
```

```js
Project: a
.model({
name: a.string().required(),
...
type1s: a.ref('Type1').array(),
}).authorization(allow => [
allow.owner(),
],),
```

2. Create a new Project item in the database, populate it with a custom type entry programatically.

```js
const list = [];

list.push({
field1: "example content",
});

await client.models.Project.update({
type1s: list,
});

```

3. Open Amplify data-manager

4. Select item -> encounter error.

Reproduce the crash in Amplify Data Manager using the custom type array and inspect the browser console error when selecting the Project item. Trace the failing data-display path from the generated stack trace; done means items containing arrays of custom types can be opened without the error screen.
