Code with my own print debugs added:

def find_unit_with_creds():
    """Find the unit thats has stored the credentials.

    :returns: unit name
    :rtype: str
    """
    unit = None
    print("CCB: unit={}".format(unit))
    for vault_unit in zaza.model.get_units('vault'):
        print("CCB: vault_unit={}".format(vault_unit))
        cmd = 'ls -l ~ubuntu/{}'.format(AUTH_FILE)
        print("CCB: cmd={}".format(cmd))
        resp = zaza.model.run_on_unit(vault_unit.name, cmd)
        print("CCB: resp={}".format(resp))
        print("CCB: resp.get('Code')={}".format(resp.get('Code')))
        if resp.get('Code') == '0':
            unit = vault_unit.name
            break
    print("CCB: unit={}".format(unit))
    return unit

def get_credentails():
    """Retrieve vault token and keys from unit.

    Retrieve vault token and keys from unit. These are stored on a unit
    during functional tests.

    :returns: Tokens and keys for accessing test environment
    :rtype: dict
    """
    unit = find_unit_with_creds()
    print("CCB: unit={}".format(unit))
    with tempfile.TemporaryDirectory() as tmpdirname:
        tmp_file = '{}/{}'.format(tmpdirname, AUTH_FILE)
        zaza.model.scp_from_unit(
            unit,
            '~/{}'.format(AUTH_FILE),
            tmp_file)
        with open(tmp_file, 'r') as stream:
            creds = yaml.safe_load(stream)
    return creds

For some reason ~ubuntu/vault_tests.yaml doesn't exist on the vault/0 unit, resulting in unit = None.

Debug output:

This ends up with a traceback that is hard to diagnose:
