Ok, assuming several things my first guess is this:
E depends on something that should be part of the DOM - in this case probably something that has to do with the data being returned from the server.
So to answer the question of why you have an error in your console, it is directly related to why you have no data being shown. Thus, figure out why you have no data being shown and you will have your answer.
It might seem circular, but it's not. Read your error logs on your server and inspect the data being sent back to the browser (if any) and make sure you are actually getting something useful and verify that its in the format that your JavaScript code is trying to parse it as.
PS: cut off screen cap = bad, show everything, a picture is worth a bazillion words - it's been increased due to inflation.
