Hi,

Thanks a lot for updating the code. I am getting below warning and logs are not being shown in human readable format:

[WARNING]: Failure using method (v2_runner_on_ok) in callback plugin (</home/i050396/new_upgrade/multidc/callback/human_log.CallbackModule object at 0x7fdb7280c828>): name 'unicode' is not

defined

can you please help with it ?

Best Regards,
Kris

I was getting this error:

[WARNING]: Failure using method (v2_runner_on_ok) in callback plugin (</home/X/callback_plugins/human_log.CallbackModule object at 0x7f3b1bbb6c50>): 'ascii' codec can't encode character u'\u25cf' in position 0: ordinal not in range(128)

The problem seems to be if type(output) == unicode is insufficient. Ansible wraps the unicode in a "ansible.vars.unsafe_proxy.AnsibleUnsafeText" class.

After the __future__ import I added from ansible.vars.unsafe_proxy import AnsibleUnsafeText
and changed the conditional to if type(output) == unicode or type(output) == AnsibleUnsafeText:

forked this and implemented an updated fix as @mark-wagner demonstrated in previous comment here. Worked for me w/o any issue @Krishna1408.

also worth noting that this callback plugin may no longer needed as the debug plugin can be used by default now, I have just switched to using that instead:
