No files after send/receive of snapshot between systems

I have two separate systems, prime and alt, on the same network in the same rack:

prime 192.168.0.100alt   192.168.0.101

Each system has a zpool running on it, created with the following sequence:

> zpool create -O encryption=on -O keylocation=prompt -O keyformat=passphrase <name> /dev/sda /dev/sdb

The <name> of each zpool is respective:

prime spoolalt   buck

On prime there is the following folder structure:

/spool   /AA     /*   /BB     /*   /test     /*

Here the /* represents a variety of elements are underneath the directory.

Additionally on prime, there are 6 datasets:

> zfs list/spool/spool/AA/spool/AA/Critical_1/spool/BB/spool/BB/Critical_2/spool/test

As of this post, alt has only the root dataset:

> zfs list/buck

And on prime I have about 100TB of storage capacity; this is not the case for alt which was an older box we decided to turn into a "backup" server for critical data. Caveat: we are a small support team cobbling things together from antiquated systems with minimum funding. As such, we only want to send snapshots of the critical data sets to the backup server.

Currently prime has the following snapshots

> zfs list -t snapshotspool@20211001spool/AA@20211001spool/AA/Critical_1@20211001spool/BB@20211001spool/BB/Critical_2@20211001spool/test@20211001

The directories Crticial_1 and Critical_2 are something on the magnitude of 40TB combined, so rather than try and build the workflow on these massive sets, the test directory was created and only has the following structure:

/test   sample.txt

I would like to send the snapshot of this dataset, namely spool/test@20211001 from prime to alt and issued the following command:

> zfs send -v spool/test@20211001 | ssh root@192.168.0.101 zfs recv buck/test

Output dialog appears saying the total size to send is 69KB and then displays a table showing some information, but nothing is put into the table under the columns and then the command line prompt appears for the next command. When I log into alt and check, I see the following results:

> zfs list/buck/buck/test> zfs list -t snapshotbuck/test@20211001

However, when I go into the mount location, there is nothing inside the test directory.

What am I doing incorrectly to send over the snapshot/datasets from prime to alt?
