Azurerm_app_service: unsupported attribute “manual_integration”

Any insight on the error below? As far as I understand, this is an issue in the state file and is managed by Terraform.

Error: Invalid resource instance data in state

on line 15:
15: resource “azurerm_app_service” “clinical_service” {

Instance azurerm_app_service.clinical_service data could not be decoded from
the state: unsupported attribute “manual_integration”.
