Title:
Neutron client expects a VALUE for all TYPEs when creating a neutron
lbaas pool with session persistence
Status in OpenStack Neutron (virtual network service):
Fix Released
Status in Python client library for Neutron:
Fix Released
Bug description:
When creating a neutron lbaas pool with session persistence TYPE as
"HTTP_COOKIE" or "SOURCE_IP" the VALUE field is not expected by the neutron
server.
1. If not given a VALUE, the client throws "the format expected is
<TYPE>:<VALUE>" error.
2. If given a VALUE, the server throws an internal server error.
3. And in cases like this we should expect a 400 error instead of a 500
internal server error.
I have pasted below the detailed log of the 2 different scenarios
using HTTP_COOKIE.
Case 1: If VALUE not given:
