I implemented Bootstrap 5 Autocomplete from https://github.com/gch1p/bootstrap-5-autocomplete I get data from Firestore my code:

async function getProductsArray() {

  let autoCompleteArray = [];

  try {

    const [productsArray, productsDefault] = await getSettingsProducts();
    productsArray.sort();
    productsArray.forEach((element, index) => {
      autoCompleteArray.push({
        label: element,
        value: element
      });

    });
  
    const field = document.getElementById('productsAutoComplete');
    const ac = new Autocomplete(field, {
        //data: [{label: "I'm a label", value: 42}],
        data: autoCompleteArray,
        maximumItems: 5,
        threshold: 1,
        onSelectItem: ({
            label,
            value
        }) => {
            console.log("user selected:", label, value);
            document.getElementById('productsAutoComplete').value = "";
        //createKitElements(label, 1);
        //console.log(label)
        inputVal(label);
        }
    });

  } catch (error) {
    console.log("Get Products Error: ", error);
    // errorInfo(error)
  }
}

It looks like it works, but not always. Sometimes "onSelectItem" returns "null"(about 25%). Even if the same element is clicked. I checked on chrome and Firefox. On Chrome, a bit better. Before I used Twitter typeahead, but it is old, so I wanted to try something new. Could you recommend any autocomplete api?
