If the pool is on top of LUKS (a relatively common configuration when ZFS and cryptsetup are both being used), then you'd need cryptsetup first. My advice is that you should either stop encrypting swap or start encrypting the whole pool. Hopefully in another (Ubuntu) release or two, we'll have native ZFS encryption and this whole things Just Works.

Timing problem? Status in zfs-linux package in Ubuntu: New Bug description: Hi, first of all: I don't know if it is a bug in cryptsetup-initramfs or zfs-initramfs or another one. The problem is that since my upgrade from bionic to cosmic the cryptsetup tries too early to setup my cryptswap device which is on a zvol. cryptsetup: Waiting for encrypted source device /dev/zvol/rpool/swap... ALERT! encrypted source device /dev/zvol/rpool/swap does not exist, can't unlock cryptswap1. ... After timeout I find myself in a initramfs-shell (initramfs). When I do zpool list there is no zpool importet. After zpool import -N rpool ^D the cryptsetup succeeds.
