"errorMessage": "[LoadBalancer] Invalid LoadBalancer objectId edge_load_balancer_application_profiles1, the valid objectId should start with the objectId prefix applicationProfile-
When the "applicationProfileId" parameter is omitted while configuring an NSX Edge Load Balancer with the PUT REST API, a default "applicationProfileId" is created. This default “applicationProfileId” is created in an incorrect format (i.e. edge_load_balancer_application_profilesX instead of applicationProfile-X).
Resolved in VMware NSX for vSphere 6.4.5.
Workaround:
To overcome this issue, specify the "applicationProfileId" with pattern “applicationProfile-<number>” while configuring the NSX Edge Load Balancer with the REST API “PUT /api/4.0/edges/{edgeId}/loadbalancer/config”.
