Describe the bug

Autocomplete field isn't loading all the data from DynamoDB (AppSync API).

When searching for BB the result box should show 23 results, but it only shows 1. I can see that the first query executed has a NextToken populated, but the UI isn't looping through the results to load all matching items from DB.

Expected behavior

When searching for an Item on Autocomplete in Data Manager, I would expect to get all results that match the filter.

Reproduction steps

1. Create the following schema

type Portfolio @model
  @auth(
    rules: [
      { allow: private, provider: [iam] }
    ]
  ) {
  id: ID!
  name: String!
  tickers: [PortfolioTicker] @hasMany(indexName: "byPortfolio", fields: ["id"])
}

type PortfolioTicker @model
  @auth(
    rules: [
      { allow: private, provider: iam }
    ]
  ) {
  portfolioId: ID! @primaryKey(sortKeyFields: ["symbol"]) @index(name: "byPortfolio")
  portfolio: Portfolio @belongsTo(fields: ["portfolioId"])
  symbol: String! @index(name: "byTicker")
  ticker: Ticker @belongsTo(fields: ["symbol"])
  entryDate: AWSDateTime!
}

type Ticker @model
  @auth(
    rules: [
      { allow: private, provider: iam }
    ]
  ) {
  symbol: String! @primaryKey
  name: String
  portfolioTickers: [PortfolioTicker] @hasMany(indexName: "byTicker", fields: ["symbol"])
}

2. Populate Ticker with more than 50 items (you can retrieve a list of Tickers here: Tickers; the stocks property will give you enough to start.
3. Open Amplify Studio and go to Data Manager
4. Create a new Portfolio without adding any Tickers
5. Change the type to PortfolioTicker
6. Click on Create new PortfolioTicker
7. Search for BB on the ticker autocomplete field.

The expected result should contain many instances of tickers with BB, but it doesn't show them all.

I believe I've found the culprit, if Amplify Studio uses the autogenerated Autocomplete from Amplify-UI.
This is the code generated by Amplify-UI (Figma-to-code) for a autocomplete field:

  const fetchTickerRecords = async (value) => {
    setTickerLoading(true);
    const newOptions = [];
    let newNext = "";
    while (newOptions.length < autocompleteLength && newNext != null) {
      const variables = {
        limit: autocompleteLength * 5,
        filter: {
          or: [{ name: { contains: value } }, { symbol: { contains: value } }],
        },
      };
      if (newNext) {
        variables["nextToken"] = newNext;
      }
      const result = (
        await client.graphql({
          query: listTickers.replaceAll("__typename", ""),
          variables,
        })
      )?.data?.listTickers?.items;
      var loaded = result.filter(
        (item) => !tickerIdSet.has(getIDValue.ticker?.(item))
      );
      newOptions.push(...loaded);
      newNext = result.nextToken;
    }
    setTickerRecords(newOptions.slice(0, autocompleteLength));
    setTickerLoading(false);
  };

The problem here is that
result.nextToken doesn't exist. The nextToken property is outside of the items list.
