Homing Projectile Graphing

Has anyone been able to get a projectile to randomly home in on a target after launching? I see it as a check mark option, have tried several graphs and tried utilizing some support for Unreal graphing. But I can’t seem to get it to seek a target. The subtext reads: “Homing target component must be set after projectile is spawned.” How exactly does one go about doing this? Willing to pay for the class or the graph work. Thank you.
