How to ignore "Computed solution is approximate" when planning robotic arm trajectories

i am trying to get a Panda robot arm (simulated in Gazebo) to move from A to B without flipping the endeffector (eg. while holding a cup of water). I use IKFast as kinematic solver (solve_type: Manipulation1) and OMPL with RRTConnect as planner. It seems that RRTConnects finds a solution but it is rejected because it is approximate. What does that mean? And how to force it to accept it?

I am also facing this same issue, when using TRRT as the planner.
