1,23998,CLI command failed - internal.

I was trying to restore a VM image to vCenter using MCCLI.  I got this error.  Could not understand what this error is, but upon further verification, it seems I was trying to restore a VM that is not exisitng (previously existing, but was deleted from Avamar).  So if you get the same error, please check your inputs first.  I expect MCCLI should say that machine is not existing.

Avamar 6.1 mccli document says the following information, but not that useful.

Generic mccli command failed message

Some errors and failure conditions are not associated with specific event codes. As a

result, when these errors and failure conditions occur, the generic event code for an mccli

command failed appears. For example, missing arguments or failed connection from the

MCCLI to the MCS generates the same 23998 event (mccli command failed).

In my case, the arguments were not missing, but were incorrect.  In 1,23998; 1 is the return code and the error number is 23998.

Thought of sharing in the community who might get the same error.
