Media Request Analytics Failed

Question

I got the following error in the log files of my upgraded site:

2628 2016:12:09 13:07:13 ERROR Media request analytics failed
Exception: System.InvalidOperationException
Message: Tracker.Current.Session.Interaction is not initialized
Source: Sitecore.Kernel
   at Sitecore.Diagnostics.Assert.IsNotNull(Object value, String message)
   at Sitecore.Analytics.Media.MediaRequestEventHandler.OnMediaRequest(Object sender, EventArgs args)

Any ideas what is the cause of this?

Answer 1

We ran into the same issue on our CM server (Sitecore 8.1 Update 3, robot detection disabled) and found we had to do the following as detailed on a different documentation page https://doc.sitecore.net/sitecore_experience_platform/setting_up__maintaining/xdb/configuring_servers/disable_robot_detection_on_a_content_management_server

Change:

<configuration>
  <system.webServer>
    <modules>
      <add type="Sitecore.Analytics.RobotDetection.Media.MediaRequestSessionModule, Sitecore.Analytics.RobotDetection" name="MediaRequestSessionModule" />
    </modules>
  </system.webServer>
</configuration>

to

<configuration>
  <system.webServer>
    <modules>
      <add type="Sitecore.Analytics.Media.MediaRequestSessionModule, Sitecore.Analytics" name="MediaRequestSessionModule" />
    </modules>
  </system.webServer>
</configuration>
