Can't exit Vehicle

I have a problem with spawning a player character after I press button to enter/exit car. Debugging shows everything is connected and working - but player is not respawning.
I followed tutorial:

https://docs.unrealengine.com/latest/INT/Gameplay/HowTo/PossessPawns/Blueprints/index.html

I cannot get this point working:

  1. Drag off the As Sedan C pin and add the Set Player node, then drag off Player and add a Get Reference To Self node.

This is screen shot of error log.

Sorry for my english.
Thank you for any help in advance.

Hey -

The “Accessed None” error is a known issue that our developers are currently investigating. You may also want to take a look at this video on setting up blueprints to be able to communicate with each other: - YouTube

Thank You very much for your quick reply, I will check above video.

Thank you for your help.
I have sorted out my problem. I was trying to get reference to vehicle BP named “MyBuggy” - only to discover there was 2 of blueprints created with same name but stored in different folders and one of them was empty. After deleteing empty blueprint problem was sorted.
It was my own fault .
