Answer 1

I could not reproduce your issue, it works on my side.

Try to update the Az.ServiceFabric with the command below, my version is 2.0.1.

Update-Module -Name Az.ServiceFabric -Force

In azure keyvault, I use a self-signed certificate, make sure you use the SecretIdentifier below.

Then use the powershell and check the result in the portal.

Add-AzServiceFabricClusterCertificate -ResourceGroupName '<group-name>' -Name 'joyfabric' -SecretIdentifier 'https://joykeyvault.vault.azure.net/secrets/cer135/23c6706daeab47e59caca2431ad96a1c'
