Description

When creating a downgrade, the web client is still passing IDs which are no longer supported:

Bad request received: The properties [Upgrade/from_version] specified in the request or predicate are not supported for the resource type Upgrade.

To initiate a downgrade, the following information can be passed:

{
  "Upgrade": {
    "skip_failures": "false",
    "skip_service_check_failures": "false",
    "skip_prerequisite_checks": "true",
    "upgrade_type": "NON_ROLLING",
    "direction": "DOWNGRADE"
  }
}

Notice that there's no need no specify a version; the downgrade by nature must work off of the last failed upgrade.
