BUG: REST API update_discovery_phase is not working for state "monitored"

The API call to update the discovery state of a service is not working for the state “monitored” if you want to enable the monitoring for a found service. The other action ignore is working as expected.


curl -X 'PUT' \
  'http://localhost:5000/cmk/check_mk/api/1.0/objects/host/localhost/actions/update_discovery_phase/invoke' \
  -H 'accept: */*' \
  -H 'Authorization: Basic authstring' \
  -H 'Content-Type: application/json' \
  -d '{
            "target_phase": "monitored",
            "check_type": "df",
            "service_item": "C:/"

Leads to a change inside the monitoring but without enabling the filesystem check for C:.
The response from API is as expected a 204 without any output.

Thank you for reporting this issue. We’ll investigate this and will update this post once we have more information.
