Hi Thomas,
First, please ensure that you have retrieved correct taskId for completed
tasks. Then you should be able to get completed task instance by sending a
GET request to *bpmn/history/historic-task-**instances/<TASK_ID>. *You
cannot get completed task instance details using */runtime* service. Hence
it returns 404.
We are not supporting to get comments by historic task instance ids as it
is not specified in the activiti spec[1].
You can get comments for historic process instance by
*/bpmn/history/historic-process-instances/{process-instance-id}/comments/*
and then it returns all the comments. In the response array you can find
completed tasks also. It contains *processInstanceUrl* and by invoking that
url you can get comments for completed tasks.

Thanks
