Filtering Fortinac-F API hosts

Hi!

I'm trying to list spesific host types usig API;

curl -k --location --request GET 'https://x.x.x.x:8443/api/v2/host?filter=iconType==camera' --header 'Authorization: Bearer XXXXXXX'

(just using at this example icon type, that is one differentiator between host types in our case)

This filter doesn't work. Am I doing something wrong?

Also one interesting thing is, that only 25 hosts are shown, when no filter is used...

Although the last line tells:

..."filtered":4865,"total":4865}

NAC version 7.4.0
