New-AzDeployment : Cannot retrieve the dynamic parameters for the cmdlet when deploying to different subscription then the subscription storing the templateSpec

[stweb1963]

If you deploy to a different subscription then the one the templateSpec is stored you receive the following error

New-AzDeployment : Cannot retrieve the dynamic parameters for the cmdlet. Operation returned an invalid status code 'NotFound' At line:1 char:1

• New-AzDeployment -TemplateSpecId /subscriptions/c304833c-8a28-41f4-96 ...

• 
  + CategoryInfo          : InvalidArgument: (:) [New-AzDeployment], ParameterBindingException
  + FullyQualifiedErrorId : GetDynamicParametersException,Microsoft.Azure.Commands.ResourceManager.Cmdlets.Implementation.NewAzureSubscriptionDeploymentCmdlet

We would store/manage all our templateSpecs / versions within a single HUB subscription

All deployments would consume this each managed templateSpec/version for any deployment across all subscriptions

The fix for this has now been released with v5.2.0
