Solution

You should update your code:

<argument name="data" xsi:type="array">
    <item name="js_config" xsi:type="array">
        <item name="provider" xsi:type="string">event_form.event_listing_data_source</item>
        <item name="deps" xsi:type="string">event_form.event_listing_data_source</item>
    </item>
    <item name="label" xsi:type="string" translate="true">Event Form</item>
    <item name="layout" xsi:type="array">
        <item name="type" xsi:type="string">tabs</item>
    </item>
</argument>

<dataSource name="event_listing_data_source">
    <argument name="dataProvider" xsi:type="configurableObject">
        <argument name="class" xsi:type="string">Magento\Framework\View\Element\UiComponent\DataProvider\DataProvider</argument>
        <argument name="name" xsi:type="string">event_listing_data_source</argument>
        <argument name="primaryFieldName" xsi:type="string">events_id</argument>
        <argument name="requestFieldName" xsi:type="string">id</argument>
    </argument>
    <argument name="data" xsi:type="array">
        <item name="js_config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Ui/js/form/provider</item>
        </item>
    </argument>
</dataSource>
