zfs export to another server running TrueNAS not working. Thoughts?

[ShadowLeague]

I have a zfs pool on my unRAID box, and I'm wanting to export it (while still having access to the data) to a remote system currently running TrueNAS. I've configured a ZFS Pool on the TrueNAS box, enabled SSH, and confirmed I can SSH and make a new folder on the TrueNAS box from the unRAID system. I keep running into issues using zfs send, similar to this
 

root@virtunraid:~# zfs send -R slow@pre-migration-snapshot_17sep24_231pm | sshpass -p 'Password' ssh [email protected] sudo -S zfs recv slow
cannot send slow@pre-migration-snapshot_17sep24_231pm recursively: snapshot slow/vmz@pre-migration-snapshot_17sep24_231pm does not exist
warning: cannot send 'slow@pre-migration-snapshot_17sep24_231pm': backup failed

root@virtunraid:~# zfs list -t snapshot

slow@pre-migration-snapshot_17sep24_233pm     0B      -     3.22T  -

I'm not sure why it's referencing a snapshot that doesn't exist. Maye some compatibility issues between unRAID and TrueNAS? The snapshots listed are for the pool - the plan was to export everything in one swoop while keep the data available.

Try replicating a dataset instead, never tried to replicate a pool, not sure if it works the same.
