Prevent collision on the player cause projectile stop

Hello,
I am French, sorry for my bad English.
I am trying to prevent the projectile to collide with my player.
It works when I test the owner of the projectile with other components on the iht event.
But the projectile stops immediately.

I just made a test if the owner of the projectile (which I defined on the spawn node being the player), and do nothing if true.

I don’t understand where is the problem.

Can you help me ? Thank you !

I solved this problem with the node ‘Ignore Actor when moving’ on the event begin play of the projectile blueprint…
