Model missing fields in creation mutation

[arlyon]

Describe the bug

I have a schema:

type PageBlock {
    title: TranslateableText!
    titleAudio: Int!

    icon: String!
    headerImage: AWSURL
    blocks: [Block!]!
}

type ParagraphBlock {
    text: TranslateableText!
    audio: Int!
}

type HeaderBlock {
    text: TranslateableText!
    audio: Int!
}

type ImageBlock {
    url: AWSURL!
}

union Block = ParagraphBlock | HeaderBlock | ImageBlock

type Page @model {
    id: ID!
    page: PageBlock!
    ... more
}

One of the fields of my Page model is a PageBlock, which has 0 or more sub-blocks. I can query these just fine:

query {
  getPage(id: "my_page") {
    page{
      blocks{
        ... on HeaderBlock {
          text {source}
          audio
        }
        ... on ParagraphBlock {
          text {source}
          audio
        }
        ... on ImageBlock {
          url
        }
      }
    }
  }
}

I can't however create page blocks. How do I do this?

Amplify CLI Version

4.19.0

Expected behavior

I would expect to be able to create unions.
