Flow designer error after moving to another instanceIssue After the flow is migrated from one instance to another through update sets, on opening the flow below error message is received on the destination instance: CauseThe sys_id mentioned in the error message, This is of a custom action created in the source instance and the action was not migrated to the destination beforehand and the flow was migrated directly. For the error message "Action Type Definition with Id of <sys_id> is missing (order: 2)", the issue is with the action not present in the table sys_hub_action_type_snapshot and sys_hub_action_instance_list in destination instance. https://<instance_name>/sys_hub_action_type_snapshot_list.do https://<instance_name>/sys_hub_action_instance_list.doResolutionThe issue is with the custom action not captured in the update set to migrate because of which the error is received. Please recreate the action and capture it on a update set and then migrate it. While migrating the flow please keep in mind that all the relevant details of the flow are migrated in the single update set so there is no discrepancy of any configuration on the flow.
