Problem with Materialize chips-autocomplete

I have been trying to get chips autocomplete to work as part of a project.

I have stripped code right back to remove any odd effects and replicated code as on the Materialize site. As in attached code I can get autocomplete to work as expected but not with chips.

I have tried with Chrome and Edge browsers and various combinations of tags and class names but still unable to make it work.

So now I need some help!

What have I missed?

        document.addEventListener('DOMContentLoaded', function() {
                options={"data": {"abel":null,"baker":null,"charlie":null},
                         "placeholder":'fred'}
        console.log (options) 
        var autoElems = document.querySelectorAll('.autocomplete');
        var attemptElems = document.getElementById("attempt");
        var chipsElems = document.getElementById("chips-autocomplete");

        var auto = M.Autocomplete.init(autoElems, options);
        var chips = M.Chips.init(chipsElems, options);
        });
    </script>

Solution

The data init for chips-autocomplete is incorrect. From the docs:

  $('.chips-autocomplete').chips({
    autocompleteOptions: {
      data: {
        'Apple': null,
        'Microsoft': null,
        'Google': null
      },
      limit: Infinity,
      minLength: 1
    }
  });

With Vanilla JS:

document.addEventListener('DOMContentLoaded', function() {
    var elems = document.querySelectorAll('.chips-autocomplete');
    var instances = M.Chips.init(elems, {
        autocompleteOptions: {
          data: {
            'Apple': null,
            'Microsoft': null,
            'Google': null
          },
          limit: Infinity,
          minLength: 1
        }
      });
  });

you are simply setting data (in quotes, when there should be no quotes). It should be autocompleteOptions as an object, and then data inside this.
