Unable to remove acknowledgement using API

Icinga 2
1

I want to remove an ACK for a specific service and always get the answer:

{"error":404,"status":"No objects found."}

Here’s the curl command I’m sending:

curl -k -s -S -i -u ticket-autoack:REDACTED -X POST \
    -H 'Accept: application/json'\
    'https://icinga2:5665/v1/actions/remove-acknowledgement' \
    -d '{ "type": "Service", "filter": "host.name==\"THE HOSTNAME\" && service.name==\"THE SERVICENAME\"" }'

Of course I’ve tripple-checked Hostname and Servicename, and for testing the filter I tried the following:

curl -k -s -S -i -u ticket-autoack:REDACTED -X POST \
    -H 'Accept: application/json' \
    -H 'X-HTTP-Method-Override: GET' \
    'https://icinga2:5665/v1/objects/services' \
    -d '{ "type": "Service", "filter": "host.name==\"THE HOSTNAME\" && service.name==\"THE SERVICENAME\"" }'

This returns the object as expected, including:

        "acknowledgement": 2,
        "acknowledgement_expiry": 1731989586,
        "acknowledgement_last_change": 1730779987.021408,

So I don’t see what’s wrong with my filter, as it works with objects/services but not with /actions/remove-acknowledgement.

The acknowledgement I try to remove does have an expiration date.

I found the cause by myself:

The API-User had no permission to remove acknowledgements :man_facepalming:

I would expect a different error message, though.
