Materialize CSS autocomplete with JQuery UI error Uncaught TypeError: this.source is not a function

Question

I'm using Materialize CSS library and in that, there is an option to make autocomplete dropdown (you can find that at the end of the page)

if I try to use that, when I typing something it is showing me this error

Uncaught TypeError: this.source is not a function
at t.(anonymous function).(anonymous function)._search (http://localhost/imgup/js/jquery-ui.min.js:2345:101)
at t.(anonymous function).(anonymous function)._search (http://localhost/imgup/js/jquery-ui.min.js:139:77)

at i (http://localhost/imgup/js/jquery-ui.min.js:302:62)

I searched for this question but I didn't find any useful answers

this is my Materialize CSS - HTML code

<input type="text" id="autocomplete-input" class="autocomplete">

and this is javascript for autocomplete

$('input.autocomplete').autocomplete({
data: {
"Apple": null,
"Microsoft": null,
"Google": 'http://placehold.it/250x250'
},
limit: 20, // The max amount of results that can be shown at once. Default: Infinity.
onAutocomplete: function(val) {
// Callback function when value is autcompleted.
},
minLength: 1, // The minimum length of the input for the autocomplete to start. Default: 1.
});

and there are some screenshots that where I'm getting error as below error log

Error in console:

Which version of jQuery/Materialize are you using? Check out this pen where it's working:

Did you wrap your jQuery code in something like $(document).ready()?
