[VMC] Unable to change the Connected Gateway of Segment to None

Products

• VMware Cloud on AWS

Issue/Introduction

• For the NSX segments which were created via HCX L2E workflow and later cutover in VMC, the following error is thrown when attempting to change "Connected Gateway" to "None":-
  • Error: Could not resolve type id 'Segment' as a subtype of `ChildPolicyConfigResource`: known type ids = [ChildAntreaTraceflowConfig, ChildBfdProfile, ..., ChildSegment, ..., ChildVpcSubnetPort] (for POJO property 'children')
  • 
• Creation of native NSX segments with "Connected Gateway" set to "None" continues to work. 
• For existing native NSX segments, changing "Connected Gateway" to "None" also works.

Environment

VMware Cloud on AWS

Cause

This is caused by VMC-specific NSX UI bug where the payload does not contain: "resource_type": "ChildSegment"

Resolution

• This is a known bug in VMC-specific NSX UI which is a part of NSX product bundle. Formal bug fix would come in as a bundle update in a future release (no ETA).
• Workaround: Create a native NSX segment with "Connected Gateway" set to "None".
