Livestatus mismatch with Icinga in versions v3.06-2+

[OffbeatFocus]

Describe the bug Thruk API throws Error 500 after upgrading to Version v3.06-2 (or newer) when accessing objects via API endpoint, e.g. /thruk/r/services/hostname/servicename with backend Icinga.

Error message:

Thruk Version v3.06-2 (or newer)

To Reproduce Steps to reproduce the behavior:

1. Have current version of Icinga
2. Install & Configure Thruk v3.06-2 (or newer)
3. Try accessing object data via API endpoints (/thruk/r/hosts or /thruk/r/services)
4. See error

Expected behavior API endpoints expose object data in json format without throwing error message

Screenshots not applicable

Desktop (please complete the following information): irrelevant

Additional context The bug is caused by commit a3bc662 Reversing this commit via patch -R fixes the issue (but also removes the new features of course)

I don't know what the feature provides, but Icinga's official Appendix says the livestatus column's name is comments_with_info, instead of comments_info which would explain the error message at least.

Icinga Version: 2.14.0-1.el7 (but it happens in 2.13.6 too)

Thanks, should be fine again with the next release. There is indeed no comments_info column in icinga, that's a virtual column added by Thruk to provide a flat string with the comments for example to put it into a grafana table which cannot display nested structures.
