Activation Unlock No entry found for device

when I Use a Bypass Code to Disable Activation Lock, get the error <error code="1002" message="com.apple.cds.cyclops.mdm.MDMServiceException: No entry found for device>。For this interface, I don’t know much about the guid and orgname passed in the body. I don’t know where these two parameters are obtained. I am not sure whether this error is returned for this reason。I got these two parameters from https://developer.apple.com/documentation/devicemanagement/get_account_detail, where org_name is used as orgname and server_uuid is used as guid. I don’t know if this is correct.
