Issue/Introduction

  • From the NSX UI, under Networking, the Manager Mode is being used to attach a virtual server to a Load Balancer.
  • The following error is displayed when attempting to attach to a Load Balancer:

    Json de-serialization error: property _meta is unrecognized. (Error code: 287)


Environment

VMware NSX 4.1.x

Cause

The load balancer objects were created in Manager Mode, which is deprecated and should no longer be used. Additionally, the NSX UI is inputting additional parameters (_meta), resulting in a 400 response with the error: "property _meta is unrecognized.".
