Usage of IcingaWeb2 api command returns 404, but is successful

[K0nne]

Describe the bug

When I use the icingaweb2 api, some commands return a 404, but the commands are successful executed.

To Reproduce

IcingaWeb2 2.9.6

curl -H "Accept: application/json" -u usr:pwd -X POST \
"https://fqdn/icingaweb2/monitoring/downtimes/delete-all?hostgroup_name=hostgroupname"

returns:
{"status":"error","message":"fqdn master1: Can't send external Icinga command: 404 No objects found.\nfqdn master2: Can't send external Icinga command: 404 No objects found."}

IcingaWeb2 2.12.1

curl -H "Accept: application/json" -u usr:pwd -X POST \
"https://fqdn/icingaweb2/monitoring/downtimes/delete-all?host_name=hostname"

Interestingly it works for single services with ?host=<hostname>&service=<servicename>

curl -H "Accept: application/json" -u usr:pwd -X POST \
"https://fqdn/icingaweb2/monitoring/downtimes/delete-all?hostgroup_name=hostgroupname"

returns:
{"status":"error","message":"fqdn master1: Can't send external Icinga command: 404 No objects found.\nfqdn master2: Can't send external Icinga command: 404 No objects found."}

Expected behavior

Successful execution should be reflected as such.

Hi,

this is hardly an issue with Icinga Web. The result you get is what Web gets from Icinga's API.

I don't know what the issue is, but it seems to me that some of the hosts in the group are not found, and some are. Or that some of the hosts have no downtime, but some have.

Looked at it again. This changed with Icinga 2.13.0 due to Icinga/icinga2#8913 and Web still tries to remove child downtimes.
