CLI mode switch failed warning on Cisco FMC discovery

Good afternoon.

I'm setting up Unimus to backup the configs of my switches, FTD devices, etc and so far it's all working beautifully.
I was hoping to add our Cisco FMC as well, but it is failing discovery and I'm not sure what, if anything, I can do to get past the error I am being given.
Any help would be very much appreciated. Thanks!

Error: There was no error, but CLI mode switch failed

Discovery log:
Service check:
SSH: Service available

Service connection:
SSH: Connection successful

Authentication:
SSH: Login successful

Device discovery:
Basic device info: UNSUPPORTED_DEVICE

Discovery of available CLI modes:
Enable (privilege exec) mode: NO_ERROR_BUT_MODE_NOT_SWITCHED

Disconnect:
device disconnected

Do you have the separate Enable/Configuration mode passwords entered into your Unimus (we have to treat them differently so there's 2 different kinds of Credentials Login and Configure/Enable Mode)

If you do, what you can do is go to your Zones, go to the Zone that has this device and enable Debug logging. Re-run the discovery and then pull the logs, there can be sensitive information so I highly recommend only posting relevant data or at least masking anything senstive before posting to the forum.

Thank you for the reply! It's end of the day Friday in my timezone, so I'll take a look on Mon morn and give it a try :-)
