I'm not sure if you guys have any regression testing but while this fixed an issue where a regular user with an unrestricted dashboard was getting 403s, now a regular user can see all the peers on /api/peers (without permissions) while /api/peers/<id> returns

{
    "message": "user ... has no access to peer ... under account ...",
    "code": 500
}

after clicking on a peer. I think this should be also HTTP 403 and not 500.

Rolling back to 0.28.3 (that somewhat worked) for now after getting somewhat burned by 0.30.0 and 0.30.2.
