Widgets not working for GET INVOICE from google assistant.

[mohdahk]

Hi, I am trying to integrate the App widgets to the google code lab same sample app. The get Exercise observation works perfectly fine but when i am configuring actions.intent.GET_INVOICE, It works fine from test tool. But with voice inputs like "Get my Bill in " it says "App isn't installed". Any reasons for this ? Looking for fix.
Below is the code in shortcuts.xml for get voice :

 <capability android:name="actions.intent.GET_INVOICE">
   <app-widget
        android:identifier="GET_INVOICE"
        android:targetClass="com.devrel.android.fitactions.widgets.StatsWidgetProvider"
        android:targetPackage="com.ahk.assistantsample">
        <parameter
            android:name="invoice.forService.name"
            android:key="forServiceName"
            android:required="true">
        </parameter>
        <extra android:name="hasTts" android:value="true"/>
    </app-widget>

    <intent
        android:identifier="GET_INVOICE_FALLBACK"
        android:action="android.intent.action.VIEW"
        android:targetClass="com.devrel.android.fitactions.widgets.StatsWidgetProvider">
    </intent>
</capability>
