While defending himself is a goal, or more specifically, to survive, it still puts him in the position of being reactive. In order to defend himself, he first has to be attacked. Which I think is fine for an initial goal, but how does that change into a goal which makes him-the protagonist- the one who is proactive? The one who drives the plot.
Look at ?Logan?, the film which Hugh Jackman says will be be his last turn as Wolverine. Without spoiling the film, Logan's goal is to deliver the girl to a place, while also defending her. By giving him a destination the film gives him an active goal to pursue, even as he fights off the antagonists.
Since Star Wars is once again dominating the box office, I think this video essay?which, at one part, talks about the differences between how active and passive protagonists affect a story, is particularly relevant. While I don't necessarily agree with some of the points as they are applied to the film, I do think the points he makes are correct regardless, especially applied to some other films.
My point is that for this logline, the goal which makes your character a proactive protagonist is more important than an initial goal that is a reaction to the antagonist and inciting incident.
Here's an example using elements from your logline:?After a magic trick turns his camera into a magical weapon, an ambitious journalist investigates a group of street magicians who are actual wizards for his next story. (28)
I changed the goal to him investigating, because not only does it tie in to his journalism career, but it also gives him an active goal. He chooses to actively investigate, to which the wizards must react. Since you seem to be going in the direction of the wizards trying to kill the protagonist, I ask why? Why exactly do they want to keep their magic a secret?
Something I do is to make a separate logline from the point of view of the antagonist. If you were to do that, then what is their motivation?
I hope this helps.
