im trying to programm a new ansible module. while testing i get the following error.

Traceback (most recent call last):
File “/tmp/ansible_EHl4xq/ansible_module_aix_stanza.py”, line 276, in
main()
File “/tmp/ansible_EHl4xq/ansible_module_aix_stanza.py”, line 257, in main
(changed, backup_file, diff, msg) = do_stanza(module, path, stanza, options, state, backup, create)
TypeError: ‘NoneType’ object is not iterable

i cannot see whats the particular problem here…any hints?

`
#!/usr/bin/python

-- coding: utf-8 --

from future import absolute_import, division, print_function
metaclass = type

ANSIBLE_METADATA = {
‘metadata_version’: ‘1.1’,
‘status’: [‘preview’],

}

DOCUMENTATION = ‘’’

Gruess Gott Christian,

what I did while debugging my ansible module is .

export ANSIBLE_KEEP_REMOTE_FILES=1
run ansible scipt /playbook etc

ansible-playbook -i /tmp/i /home/mslebodn/lbuild/pb/vcs_update.yml

and on target machine , find prepared ansible module and run it with pdb

[ans@r7_ms_vcs1 ~]$ find . -name ‘veritas’
./.ansible/tmp/ansible-tmp-1542277938.32-134723917146469/veritas.py
[ans@r7_ms_vcs1 ~]$ ./.ansible/tmp/ansible-tmp-1542277938.32-134723917146469/veritas.py explode
Module expanded into:
/home/ans/.ansible/tmp/ansible-tmp-1542277938.32-134723917146469/debug_dir
[ans@r7_ms_vcs1 ~]$ cd /home/ans/.ansible/tmp/ansible-tmp-1542277938.32-134723917146469/debug_dir
[ans@r7_ms_vcs1 debug_dir]$ python -m pdb ansible_module_veritas.py args

No very enlightening…!? Any glue how to translate this gibberish into something comprehensible?

A quick look seems to indicate that do_stanza may sometimes return None due to the indentation of the return at the bottom.

You would need to ensure that do_stanza always returns the tuple you expect.

The problem was indeed the wrong indentation oft he last return…thanx matt/marek for your help!
