An exception occurred during task execution. The full traceback is:

TypeError: first argument must be a string or unicode, not UnsafeProxy(AnsibleUnicode)

I tried to google around, but I didn't manage to find anything obvious. I have another test server with Ubuntu that doesn't have this problem. I also tried to install Python 2.7, but that didn't help either.

this will probably be fixed soon, we are trying to introduce a
'unsafe' type into current devel to allow for good data sanitation.

Hi Eino, this appears to be working now:

TASK [foo] *********************************************************************

changed: [localhost] => (item=foo) => {"changed": true, "cmd": "true", "delta": "0:00:00.002933", "end": "2015-09-13 20:38:31.761057", "item": "foo", "rc": 0, "start": "2015-09-13 20:38:31.758124", "stderr": "", "stdout": "", "stdout_lines": [], "warnings": []}

changed: [localhost] => (item=bar) => {"changed": true, "cmd": "true", "delta": "0:00:00.003014", "end": "2015-09-13 20:38:31.826862", "item": "bar", "rc": 0, "start": "2015-09-13 20:38:31.823848", "stderr": "", "stdout": "", "stdout_lines": [], "warnings": []}

Let us know if you continue seeing problems with this.

Thanks!

Hi James,

 

It seems that it's now working with Python 2.7 on RHEL. The distribution supplied Python (2.6) still produces the same error.
