Can't call method "children_get" on an undefined value at ./check_cdot_diff_snapmirror.pl line 121

Hi!
First, thanks very much for this splendid check set.

This may be similar to #47, but we get:
Can't call method "children_get" on an undefined value at ./check_cdot_diff_snapmirror.pl line 121., on one of our 3 clusters.

We're using the latest ONTAP SDK, so I'm not sure what might be happening here. Unfortunately I know nothing of Perl so I'm fairly useless without some pointers on collecting debug for you.

Thanks!
