In a custom rviz2 plugin, I try to display data received by client from server.

I got the following error.

terminate called after throwing an instance of 'std::runtime_error' what(): spin_once() called while already spinning

My code is similar to the following

https://github.com/introlab/rtabmap_r...

Is it possible at the moment to use client in rviz2 plugin to get receive data.

This is related to rviz2 not on user level code.

You're gonna need to either use asynchronous requests, or make a new rclcpp::Node, and create your client off of it, and spin that node.

For reference, the async_send_requestmethod does take a second argument, which is the callback to run when the response is relieved. See https://github.com/ros2/examples/blob... for an example.
