Why is not the projectile going toward the target?

I have a project where I can shoot (with a simple projectile).

Character Blueprint (generate projectile):

However I would like to be able to make the projectile go towards a specific target.

Projectile Blueprint (target definition):

And I think that with the code below I would achieve the expected effect.

Projectile Blueprint (change projectile rotation):

Some links that helped me get here (I may have let something pass):

I do not know what I’m doing wrong (based on the links above).

The projectile walks straight and visibly I see no change in its trajectory.
