Open Stack

Hi Chris,

That bug suggests there has been a fix in 12.0.8. Hopefully 12.0.16 
should have that fixed still with a bit of luck , unless the fix hasn't 
been carried over.

I can see that the bug report says there is also a fix 12.0.9 and 12.0.11.

Do you know if there is a workaround we can try for this? As ideally I 
don't want to be downgrading the openstack_ansible version.

Regards,
