Not able to override linked service properties

Hi,

I have a few issues while over riding the linked service properties in CI/CD pipeline while deploying to higher environments:

1. I have created a managed instance SQL linked service, The connection string needs to be overridden in higher environment. In CI/CD yaml file in overrideParameters, I am trying to override -ls_azure_sql_properties_typeProperties_connectionString , but getting error :
**There was an error while overriding 'ls_azure_sql_properties_typeProperties_connectionString' parameter because of 'TypeError: Cannot read property 'type' of undefined'**

2. For Azure Blob Storage linked service, we have used managed Vnet IR. The managed Vnet IR has a different name in higher environments. So we need to override this property of the linked service. When I am trying to override
-ls_az_blob_storage_properties_connectVia_referenceName in CI/CD yaml file, it gived error:
**There was an error while overriding 'ls_az_blob_storage_properties_connectVia_referenceName' parameter because of 'TypeError: Cannot read property 'type' of undefined'**

Please guide me on how to override these properties. Thanks in advance.
