The Camunda docs show `activityInstanceID` as a valid option for the `sortBy` query parameter for:

[Get Historic Activity Instances | docs.camunda.org](https://docs.camunda.org/manual/7.9/reference/rest/history/activity-instance/get-activity-instance-query/)

and:

[Get Tasks (Historic) | docs.camunda.org](https://docs.camunda.org/manual/7.9/reference/rest/history/task/get-task-query/)

when in fact, it must be: `activityInstanceId`.
