We have to use this field for tracking our work at work, so i am trying this command but the change is not being reflected:

curl -w '\n' -vvv -H "Authorization: $(cat ~/.clickup-token)" https://api.clickup.com/api/v2/task/{task} -X PUT -d '{"time_spent": 28800000}' -H "content-type: application/json"

subsequent calls to get this task show the old "time_spent" value.
