Interesting. Since space is what’s between objects, (space is not an object) it’s difficult to see how space can be bent.

Exactly. It can be bent only if it is made of what used to be called “The ether”. Which is two parts hydrogen and one part vanilla pudding.

Its the Gravity field that is bent by the mass of an object sitting in space-time. The same effect that hold our little rock in orbit around the Sun.
The bending of the space-time /Gravity field causes light to change direction, like canoe across a whirlpool, you think you've taken a straight line but in reality you've moved sideways.

Space is filled with the zero-point field of energy, so technically it is ‘something’.

That would have been a common objection pre-relativity, when all that was known was flat space-time, and massless things were thought to always go "straight". It turns out that the presence of mass induces what could be called gravity, causing a ray of light, say, to bend as it passes nearby and the time that the ray "experiences" to warp also. That is the "bend" -- things that would otherwise go straight take a curved trajectory, including light. No ether-like medium is needed, any more than there is for the sun's gravity to tug on the earth.
