Having played through from earlier versions, and into 1.16-pre2 (we hadn't tried to kill the ender dragon in those earlier versions), we hit this issue after killing the Ender Dragon.
Indeed on checking, the level.dat, the level.dat -> Data -> DragonFight -> Gateways entry was just an empty entry.
I rolled my server back to when the ender dragon was still alive (thanks, ZFS Snapshots. 😉 ) and left the server down, created a new world (using a 1.16-pre2 server), and using NBTexplorer (from the link above) navigated though to the gateways entry - and saw all 20 entries there. I clicked copy on the Gateways folder entry, then navigated to the level.dat of my existing server, got to the DragonFight spot, deleted the old gateways entry, then whilst having the DragonFight entry selected, hit paste, which dropped the fully populated Gateways entry in.
Save, startup server, and on /kill ing the ender dragon, the gateways spawned.Â
Win.
Thanks everyone who contributed - You made my 7 year old's day... He was most unhappy there was no gateway. (I'll add he was also not happy that the End city near the first gateway had no flying boat! (but that's another matter. 😉)
