Issue description

Can't create a new revision using github actions or az cli using yaml file. The case here is that secret that is in Azure Key Vault does not exists but it still deployed without any errors.

I tried to look in deployments, system logs, log workspaces and nothing. No error, no description what is going on.

Steps to reproduce

1. Create a config.yaml file

properties:
  configuration:
    secrets:
      - name: 'users-management-connection-string'
        identity: /subscriptions/[tenantId]/resourcegroups/group-tst/providers/microsoft.managedidentity/userassignedidentities/id-01-westeurope-test-identity
        keyVaultUrl: 'https://testvault.vault.azure.net/secrets/SecretDoesntExists'
template:
  containers:
    - name: 'react-app'
      image: 'testacr.azurecr.io/hello-world:latest'
      env:
        - name: OltpAppName
          value: 'Hello.App'

2. Execute a command

az containerapp update -n ca-hello-api-tst -g group-tst --yaml config.yaml

or via github actions

    - name: deploy container app
      uses: azure/container-apps-deploy-action@v2
      with:
        containerAppName: ${{ inputs.containerAppName }}
        containerAppEnvironment: ${{ inputs.containerAppEnvironment }}
        resourceGroup: ${{ inputs.resourceGroup }}
        location: ${{ inputs.location }}
        acrName: ${{ inputs.acrName}}
        acrUsername: ${{ inputs.acrUserName}}
        acrPassword: ${{ inputs.acrPassword}}
        yamlConfigPath: 'config.yaml'

Expected behavior

Get some error that Keyvault does not have a secret.

Actual behavior [What actually happened.]

No errors, just deployed.
