Debug not work?

I want to debug my project,my project is developed purely in blueprints,I found some issue and I want to debug it,with the debug filter selected,I start the game,I found the event (beginoverlap) triggered but I did not found the pulse between nodes.I wonder if I miss something?

You can follow the steps mentioned in the following link:

Just make sure that you are clicking on Play with editor window selected. If you Play in standalone game, debugger won’t work.
