How to publish a topic at shutting down a node?

1

Hi, I’m writing a node to control multiple servos, and I want it to set back to its home position when I shut it down.

I’m using rclcpp::onshutdown(Ps5Node::shutdown_callback) for this need, but I failed to publish any topic in this static shutdown_callback function. Does anyone have an example code for me to study?
