Error when i try to edit a load balancer

[Alfredo Moralejo]

Using newton rc2 versions of packages from RDO and current master HEAD of neutron-lbaas-dashboard https://github.com/openstack/neutron-lbaas-dashboard/commit/63d4427a3bad36a16c6d77e3b057db1a5a8f46a2

I've created a LB using CLI:

nova boot --image cirros --flavor m1.tiny test1
nova boot --image cirros --flavor m1.tiny test2

neutron lbaas-loadbalancer-create --name lb1 private_subnet
sleep 10
neutron lbaas-loadbalancer-show lb1 # Wait for the provisioning_status to be ACTIVE.
neutron lbaas-listener-create --loadbalancer lb1 --protocol TCP --protocol-port 80 --name listener1
sleep 10 # Sleep since LBaaS actions can take a few seconds depending on the environment.
neutron lbaas-pool-create --lb-algorithm ROUND_ROBIN --listener listener1 --protocol TCP --name pool1
sleep 10
neutron lbaas-healthmonitor-create --delay 5 --timeout 2 --max-retries 1 --type PING --pool pool1
neutron lbaas-member-create --subnet private_subnet --address 10.0.0.3 --protocol-port 22 pool1
sleep 10
neutron lbaas-member-create --subnet private_subnet --address 10.0.0.4 --protocol-port 22 pool1

When i go to lbaas dashboard i can see the LB but when i click on "Edit Load Balancer" button y get error:

Danger: An error occurred. Please try again later.

And in horizon log i see following trace:

I am running upstream newton OpenStack with the 1.0.0 version of the neutron-lbaas-dashboard from pypi.

I followed your steps and then clicked the edit button on the load balancer, which brought up the dialog and I added a description to the load balancer. It completed successfully. Can you test again with the newton release a report back if this is still an issue?

[Alfredo Moralejo (amoralej)]

The problem is related to using old panel instead of new ngloadbalancersv2 one. Using new panel, load balancer edit is working fine.
