LiQL Post Count, Kudo count, an solution count for user

Hi,

I try to show post count, kudo count and solution count for specific user on View Profile Page. I create custom component and I'm using query

SELECT messages.count(*), solutions_authored.count(*) FROM users WHERE id = '31'

I checked in API Browser in Studio, and data I recive are correct, but when I try to use it in component it breaks component (it doesn't show at all).

Here is my component code:

<#attempt>
    <#assign userViewProfileUserId = page.context.user.id />
    <#assign userQuery = "SELECT messages.count(*), kudos_received.sum(weight), solutions_authored.count(*) FROM users WHERE id='" + userViewProfileUserId +"'" />
    <#assign userData = restadmin('2.0','/search?q=' + userQuery?url('UTF-8')) />
    <div class="view-profile-user-details">
        <div class="user-statistics">
            <div class="user-statistics__item">
                <span class="user-statistics__value">${userData.kudos_received.weight}</span> likes</div>
            <div class="user-statistics__item">
                <span class="user-statistics__value">${userData.solutions_authored.count}</span> solutions</div>
            <div class="user-statistics__item">
                <span class="user-statistics__value">${userData.messages.count}</span> posts</div> 
        </div>
    </div>
    <#recover>
</#attempt>

What am I doing wrong? 

I would be grateful for your help.
