I have released my robot onto my github account.
You can have a look at the main code here:
https://github.com/Sycadellicman/Anonymous-Robot/blob/master/src/com/anonymous/engine/AnonymousEngineServlet.java
Also, I have attached the exception I am getting after adding the robot to a
wave.
As you can see, it occurs after the robot calls submit. The returned list is
indeed
empty, i.e. isEmpty() returns true. I have tried re-registering the robot on
my server
and on other servers and have made sure that I update the secrets, keys, and
domains.
I am at a lose as to what is causing this. Like I said, it was working
several days ago but
when added the robot to a wave this evening, I noticed it was misbehaving.
I really appreciate your help, Yuri. If anyone has any ideas or suggestions
given this new
information I would be more than happy to listen to them!
