The program has a runtime error

[X5reme]

Error msg is:[ERROR] [1606813160.660855737]: Do not call canTransform or lookupTransform with a timeout unless you are using another thread for populating data. Without a dedicated thread it will always timeout. If you have a seperate thread servicing tf messages, call setUsingDedicatedThread(true) on your Buffer instance.

I found something wrong.
tf2_ros::Buffer tf(ros::Duration(10));
It should be amended as：
tf2_ros::Buffer tf;
tf2_ros::TransformListener tfListener(tf);
However, after modifying the code, the path cannot be displayed.

if u r getting indexes and distance being displayed in terminal , it means algorithm is still running....
reducing map size might help.
