Hey guys,
say is this a bug or a feature ? 
Since i've updated my local fusionauth to latest 1.62.1, i run into the issue, that the application search api does not show up the oauthConfiguration.clientSecret property. I've tested same request with 1.62.0 with same result, on 1.61.2 everthing still works as expected.
So i've opened https://github.com/FusionAuth/fusionauth-issues/issues/3306 but maybe this behaviour is a new kind of security feature ?
