@elsayedelsheikh I had a similar issue until I understood that the node requires an action goal. Simply run: `ros2 action send_goal /find_objects grasping_msgs/action/FindGraspableObjects` (in separate terminal) prior to starting `basic_grasping_perception_node`....

Easiest solution to run the node without an action goal is change https://github.com/mikeferguson/simple_grasping/blob/5ca780e82d10eb5ad00ee667b9e35ced7cc15a30/src/basic_grasping_perception.cpp#L138C4-L138C50 to ```cpp if ((!find_objects_ && !continuous_detection_)) || !planner_ || !segmentation_) ```

@mjimenezm00 I came across a very similar issue while creating a task constructor node. Only the following helped me: I ran the node from a launch file and handed over...

@mjimenezm00 its loaded using the ``Task`` class. Example: https://github.com/moveit/moveit_task_constructor/blob/3b2a436f0a7e8dbb4d347960430bc26183d99535/demo/src/pick_place_task.cpp#L113 I also handed over the ``robot_description`` in the Node params. Example: https://github.com/moveit/moveit_task_constructor/blob/3b2a436f0a7e8dbb4d347960430bc26183d99535/demo/launch/run.launch.py#L23 (but this did not seem to have been necessary...
