Troubleshooting Uncaught InvalidStateError: Failed to execute 'send' on 'XMLHttpRequest': The object's state must be OPE

I must be mis-typing or something, I just can't see it.

  var xhr = new XMLHttpRequest();
    xhr.onreadystatechange = function() {
      if (xhr.readystate === 4){
        document.getElementById('ajax').innerHTML = xhr.responseText;
      }

    };

    xhr.open('GET', 'sidebar.html', true);
    function sendAJAX() {
    xhr.send();
    }

  </script>```
returns, "Uncaught InvalidStateError: Failed to execute 'send' on 'XMLHttpRequest': The object's state must be OPEN"

I think readystate should be readyState. Maybe that'll help?

Was this ever resolved? I'm having the same issue?!
