Exmplae:

TASK [nim-waku : Extract the node key from file] *****************************************************************
fatal: [boot-01.do-ams3.shards.test]: FAILED! => {}

MSG:

The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'content'. 'dict object' has no attribute 'content'

The error appears to be in '/Users/status/.ansible/roles/nim-waku/tasks/nodekey.yml': line 39, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- name: Extract the node key from file
  ^ here

Load is skipped wrongly, because generation is skipped. Maybe it should be the opposite? If generation is skipped - load from file.

If file didn't exist it also fails:

fatal: [store-01.ac-cn-hongkong-c.shards.test]: FAILED! => {}

MSG:

The conditional check 'key_generation.skipped and nim_waku_node_key is not defined
' failed. The error was: error while evaluating conditional (key_generation.skipped and nim_waku_node_key is not defined
): 'dict object' has no attribute 'skipped'. 'dict object' has no attribute 'skipped'
