Hi all, My client sends the goal but gets status ABORTED instead of SUCCEEDED and server gives following error:

[ WARN] [1337607518.317686823]: Your executeCallback did not set the goal to a terminal status. This is a bug in your ActionServer implementation. Fix your code! For now, the ActionServer will set this goal to aborted

My callback is

void startnode(const my_msgs::myGoalConstPtr& goal, Server* as)
  my_msgs::myResult result_;
  result_.result = 1;

Can anyone help me fix this problem?? Thanks in advance. Regards

This unanswered thread was closed due to 'off-topic or outdated', but I find the same error can still happen today and no other threads discuss this error. So I reopened it.

As pointed out by the error message, fix the termination state in your Action Server. In rospy sample, not calling set_succeeded can lead to the error in this question. OP asks for C++ but I haven't tried, so I can only assume that the equivalent is setSucceeded.

Hi here I leave a simple example that you can run in any robot with an odom topic that it might clear up some doubts on how this works. Basically that error appears when the result is not correctly set up in the setSucceeded method.

Here you have the GIT

Here you have the ROSJECT

Here you have a Video explaining how to launch it and the basic ideas behind this: VIDEO

And here the main elements of code for those that preffer having it here in the Forum, hope it helps:

I to got this error when I didn't use the function .set_preempted() in .is_preempt_requested() function. I can see that your code have no function during preempt is requested(i.e., goal is cancelled) and I hope this might be the error. my error got resolved, when I used .set_preemted() function in server code whenever preemted. and it resolved my error. hope this helps you. Thanks.
