panic: runtime error: makeslice: len out of rang while trying rotate-keys on 0.16

[pietrushnic]

Following issue was triggered in Setup Mode. I enrolled keys once, then trying to rotate and get following trace:

user@OST2-HW:~$ sudo sbctl rotate-keys
old configuration detected. Please use `sbctl setup --migrate`
panic: runtime error: makeslice: len out of range
