Hi,
I can recreate the issue in 2.1.0p8 when I use the fulltext parameter for this Endpoint.
You can see the Stacktrace in ~/var/log/web.log and there is also a crash Report created:
It is working fine when I use only the folder parameter or the name parameter.
This request is showing me the “Check HTTP service” Ruleset for example:
http://<myhost>/<mysite>/api/1.0/domain-types/ruleset/collections/all?name=HTTP
I will send a mail to the checkmk feedback mail for the issue with the fulltext parameter.
Best Regards
Thomas
