Event log page on OMD 5.11~2023-03-14-labs-edition nightly doesn't show logs

[infraweavers]

For example this URL:

https://omd/default/thruk/cgi-bin/showlog.cgi?host=hostname&service=Check+DHCP+Failover+State&backend=73bf8

Will return an empty page on this version:

Date    Fri Mar 17 15:40:18 GMT 2023
Version Thruk 3.05.20230314
OMD OMD 5.11~2023-03-14-labs-edition

Whereas under 5.10 it will work fine and show as expected

any service or just a single one and is there anything in the logs?

Seems to be any service at all.

If we look at the alert logs and stuff directly on OMD; there is content in them etc (and that matches the content on the mirror-pair server) it looks like it's just displaying the data that's broke
