When attempting to deploy a new Service Mesh, or update an existing Service Mesh you may encounter the following error.
This can be caused by the Network Mapping used for any of the HCX services (Management, Uplink, vMotion, etc.) being part of a non-default NSX Project.
This is a known product limitation, with no workaround available, affecting all HCX versions. This is being reviewed and planned to be incorporated in a future release
