The swagger UI curl example for tasks/{id}/run does not work

The swagger UI curl example for the tasks/run API does not work as shown:

curl -X 'POST' \
  'http://localhost:8081/service/rest/v1/tasks/42592698-59bf-4207-a208-baaeef1baea5/run' \
  -H 'accept: application/json' \
  -d ''

The "-d" parameter causes an empty content to be sent, and this fails because the content type is recognized.

Expected: The API example should either leave "-d" off, or add: -H "Content-Type: application/json"
