I am trying to provide some arguments for a particular json object but I keep seeing this error:

Object literal may only specify known properties, and 'createdData' does not exist in type '{ bookId: string; createdBooks: []; }[]

I don’t really understand the layout of this method below so just wanted to ask how the argument should be populated. It’s the [] that throws me at the end of this method

export async function settleBooks(
  createdData: { bookId: string; createdBooks: [] }[],
) {
  for (const book of createdData) {
    await settleBooksResulted(book.bookId, book.createdBooks);
  }
}

Below is how I am calling the method with the object included:

    const books = await settleBooks({
  createdData: {
    bookId: '8e3e7878-da38-43f4-a033-8cd9e37fa5c3',
    createdBooks: [
      {
        booksCreated: [
          {
            bookId: '8e3e7878-da38-43f4-a033-8cd9e37fa5c3',
            selectionId: 'd9767337-f9f6-4d05-83f4-48d5440eaa9b',
          },
        ],
      },
    ],
  },
});
