Trying to cancelGoal() when no goal is running. You are incorrectly using SimpleActionClient

This is the error I get when I send a goal. I have subscribed to callbacks and I get a callback as soon as the goal goes active. So it surely does go active. Also, getStatus() fails similarly. But the state is described as LOST.

Please explain. I will provide additional information as necessary.

Thank You.

I am creating another SimpleActionClient local variable in a member function. The Class already has a member. So, I send the goal using the local variable, where as I try to cancel it using the Class variable. It can never work. Now, I am able to Pre-empt the goal. Sorry for the trouble. Problem solved.

maybe you have already reached the goal when you try to send the cancelGoal() command

No. We have a high tolerance. Our Tolerance is about 0.3m and that is more than what amcl uses. Also, we try to getState() immediately after the goal becomes active. It gives an error at that point.
