Steps to recreate the issue: 1) Build ovsdb master code base and start the controller and you should see the above exception. |

L2 connectivity breaks because all the required flows are not getting installed because of this exception. |

I am able to reproduce the issue with a custom security group, but not with the default. It seems to be a timing issue. The security group create is called along with a port create not when the SG is created from horizon. So there are chances that empty value is returned when port create tries to do retrieve the security group info in response to a Southbound Event. I am analyzing more on it. Will add a try catch to fix issue with other flows. |

steps to reproduce: source openrc admin admin keystone tenant-create --name=tenant1 --enabled=true 2> /dev/null keystone user-create --name=user1 --pass=user1 --email=user1@example.com 2> /dev/null keystone user-role-add --user=user1 --role=member --tenant=tenant1 2> /dev/null TNT1_ID=$(keystone tenant-list 2> /dev/null | grep '\s'tenant1'' | awk ' {print $2}') neutron net-create ext1 --router:external --tenant_id=${TNT1_ID} \ |
