Constr is not a constructor Magento 2

Question

I simply want to add js for my custom module but I'm getting this error:

layout.js:137 Uncaught TypeError: Constr is not a constructor

The hello.js file will still work, console.log will still work, however, I still get the error above. Any idea?

requirejs-config.js

var config = {
map: {
    '*': {
        emlhello          : 'EML_CityAutocomplete/js/hello'
    }
}};

hello.js

define([
    "jquery"
], function($){
    "use strict";
    console.log('asdasd');
   return true;
})

And I'm trying to call it via layout xml

<referenceBlock name="checkout.root">
        <arguments>
            <argument name="jsLayout" xsi:type="array">
                <item name="components" xsi:type="array">
                    <item name="checkout" xsi:type="array">
                        <item name="children" xsi:type="array">
                            <item name="autocomplete" xsi:type="array">
                                <item name="sortOrder" xsi:type="string">0</item>
                                <item name="component" xsi:type="string">EML_CityAutocomplete/js/hello</item>
                            </item>
                        </item>
                    </item>
                </item>
            </argument>
        </arguments>
    </referenceBlock>
