gravity isn’t a force, it’s the curvature of space-time itself.
light follows a perfectly straight line through vacuum. the space itself isn’t straight.
like drawing a straight line on a flat paper, if you roll the paper, that line is still straight within it’s medium.

But isn’t the gravity bending the space, so the light itself is travelling straight but seems curved to the observer?

Hmm, I’m not actually sure. Are we also ignoring refraction and reflection because the path is straight between those? If we’re talking discrete photons, you may be correct about each segment in its path being perfectly straight, but I’m not a theoretical physicist.

“through vacuum”
