AnsibleUndefinedVariable: 'unicode object' has no attribute 'options'

I've got this error and I can't solve it!

TASK [ansible-autofs : Create map-files] ******************************************************************************************************************
failed: [m2m_appli_1] (item={'value': {u'path': u'/nfs', u'options': [u'ghost', u'timeout=30']}, 'key': u'nfs'}) => {"ansible_loop_var": "item", "changed": false, "item": {"key": "nfs", "value": {"options": ["ghost", "timeout=30"], "path": "/nfs"}}, "msg": "AnsibleUndefinedVariable: 'unicode object' has no attribute 'options'"}
