I am using flowable and try to get the form of a historic task instance but it is not working with a exception.

` [GET] /cmmn-api/cmmn-history/historic-task-instances/TSK-fd360de9-c76e-11eb-9842-2aeb3a4583af/form`

```auto
{"message":"Internal server error","exception":"A process task id or process instance id or scope id should be provided"}

```

Do we have other way to get the form of a task which is completed?
