Got a callback on a goalHandle that we're not tracking

Hello there
I am using ros for robot arm. My robot arm has 6 joints, I send 50°, 50°, 50°, 50°, 50°, 50° to these joints.
Joints always go to these degrees but sometimes I get an error like this;

Got a callback on a goalHandle that we're not tracking. This is an internal SimpleActionClient/ActionClient bug. This could also be a GoalID collision

How can i solve this problem.

SimpleActionServer only handles one request at a time. This warning hints that you have two different nodes trying to use the ActionServer at the same time, or you are making a new request before the prior one has fully completed.
