Hi @thennarasud from the provider doc: there's another property customer_managed_key_identity_id with following description:

(Optional) Specifies the ID of the user assigned identity associated with the Customer Managed Key. Must be supplied if customer_managed_key_id is set.

While I agree there might be a validation / error handling bug here, can you please try supply this property to check if this can solve your problem?

Hi @gerrytan (Gary), I have used this property also in my code, also I have tried updating this value with a new user msi and modified statefile to reflect with `customer_managed_key_identity_id' however still its throwing the parsing error.

I doubt whether this is the Terraform issue, because eventhough i have updated the statefile with `customer_managed_key_identity_id when i checked the ADF JSON file, still my ID is showing as empty. I am not sure whether the issue is residing.

Thanks for your insight.
