Folks something tells me this is going to be a "D'Oh!" moment, but I'm baffled.
I had a simple requirement to support an ongoing project that requires the creation of a snapshot, and a CIFS share referencing that snapshot, over a series of days. Snapshot and share name naming convention is a simple <YYYYmmdd-<string> and <YYYYmmdd-<string>$>
respectively.
The intention is to create both snapshot/share a little after midnight each day until the project ends and they are no longer needed. Simple enough, right?
Well, when I run these commands via SSH from a prompt on a Linux box, everything works just fine:

[root@foo01 ~]# /bin/ssh admin@foo 'snapshot show -vserver foo3 -volume Foo04 -snapshot 20231003-foo '

However, running a script (sh or bash, makes no difference in this case), I get this when it runs. It actually doesn't matter what ONTAP command I send, they all give the same "Vserver name: Invalid." error (the
/bin/ssh lines are just echo statements in the script so I can see that it's building and sending the right command line):
/bin/ssh admin@foo 'snapshot create -vserver foo3 -volume Foo04 -snapshot 20231003-foo -expiry-time 11/02/2023 00:00:00'

The script is so simple it's embarrassing. Define a few variables and optargs, build 3 simple SSH commands to send to the toaster, and run them. Everything up until these commands reach the toaster is working as expected. It just breaks when it gets there.
