Just as I suspected; it's region-specific. I ended up buying the downloadable Battlefront from the PS Store, and now I can play the VR mission on my US PS4.
Lesson learned... At least I get to fly around in an X-Wing now!

I'm pretty sure it doesn't have to be the downloadable version. I bought the physical disc from Amazon, which was region 2. Although it was playable on my US (region 1) PS4, the VR mission was incompatible, either because they didn't build support for region 2, or because there was a region mismatch with the game and my system.
I have just purchased Star Wars Battlefront VR compatible version. I was really looking forward to the new VR area until I noticed that the redeem codes EXPIRED 18.11.2018!!!!!! I have only just purchased this, so does that mean I cannot access the new locations??
Just downloaded battlefront 2 from ps plus. Downloaded the vr missions separately but it remains as “waiting to install” so I can’t play it. I assume it should work with this version.
