Hi Henrik,
thanks for your answer.
The answer is:
* => $data_sync['ssh_key']
Without interpolation the resource is created as it's areal hash... (you
can't imagine how much time I spent in this one.... Fun fact: the notify is
correct)
* The localdata key does not exists in the define as it's the main key of
the hash passed from the main class.
Thanks a lot for your answer.
Best,
Arnau
