I am trying to use the with\_inventory\_hostnames lookup plugin, but it keeps failing with the folllowing error: “A vault password must be specified to decrypt /opt/ansible/group\_vars/secure\_vault”

A workaround was to modify the LookupModule to provide the vault\_password to the inventory. Is this the correct approach?

`

class LookupModule(object):

def **init** (self, basedir=None, \*\*kwargs):  
self.basedir = basedir  
if ‘runner’ in kwargs:  
self.host\_list = kwargs[‘runner’].inventory.host\_list  
self.vault\_pass = kwargs[‘runner’].vault\_pass  
else:  
raise errors.AnsibleError(“inventory\_hostnames must be used as a loop. Example: "with\_inventory\_hostnames: 'all'"”)

def run(self, terms, inject=None, \*\*kwargs):  
terms = utils.listify\_lookup\_plugin\_terms(terms, self.basedir, inject)

if not isinstance(terms, list):  
raise errors.AnsibleError(“with\_inventory\_hostnames expects a list”)  
return flatten(inventory.Inventory(self.host\_list, vault\_password=self.vault\_pass).list\_hosts(terms))

`
