“Error while getting logical router” when querying NSX logical-router diagnosis information from API

Products

• VMware NSX

Issue/Introduction

• Using NSX API to query logical-router diagnosis information returns the following error:
  • API call:  GET /api/v1/transport-nodes/<transport-node-id>/node/logical-routers/diagnosis



    {
        "error_code": 36941,
        "error_message": "Error while getting logical router",
        "module_name": "node-services"
    }

Environment

NSX version prior to 3.2.4

Cause

Issue is caused by incorrectly parsing logical-router "failover mode" section.
If transport node contains logical-router with "failover mode" n/a, this issue may be encountered.

To verify, ssh into edge transport node and run the following commands:

edge> get logical-router <UUID> high-availability status
Service Router
UUID                  : <UUID>
state                 : Active
type                  : TIER1
mode                  : A/S
failover mode         : n/a  <-----
