    Hi iftomkins

     

    Looks good, however I'd recommend wrapping in <attempt> tags to catch any errors should something go wrong. It is highly unlikely as this is fairly simple logic however this should cover most scenarios.

     

    <#attempt>
<#if messageAuthorId == -1 >
    <#assign avatarUrl = "/html/assets/icon_anonymous_message.png" />
<#else>
    <#assign avatarUrl = rest("/users/id/${messageAuthorId}/profiles/avatar/url").value />
</#if>
<#recover>
        <!-- what to do if the above logic fails or there is an error -->
    <#assign avatarUrl = "/html/assets/icon_anonymous_message.png" />
</#attempt>

    Wrapping in this around your code will catch any exceptions in the code should they occurr and instead of displaying the error it'll default to the anonymous user avatar you have specified.
