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

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
