How to return unauthorized response from before hook in feathersJS - node.js

Question

I have parts of app (modules) that gonna be forbidden for certain people, so I wanna check that in before hook and send unauthorized response if its needed.
I'm successfully throwing error on backend, but on my frontend I still get successful response as if there was no error.
Here is how my code looks like:
1.Function that checks if app is forbidden for user that sent request:
function isAppForbidden(hook) {
let forbiddenApps = [];
hook.app.services.settings.find({
query: {
$limit: 1,
$sort: {
createdAt: -1
}
}
}).then(res => {
let array = hook.params.user.hiddenApps;
if(array.indexOf('qualitydocs') >= 0 || res.data[0].forbiddenApps.indexOf('qualitydocs') >= 0) {
hook.response = Promise.reject({error: '401 Unauthorized'});
//this part is important, the rest not so much
//what im expecting to do here is just to return unauthorized response
}
});
return hook;
}
But this for now just throws error on backend like:
"error: Unhandled Rejection at: Promise Promise {
{ error: { code: '401', message: 'Unauthorized' } } } code=401, message=Unauthorized"
And frontend still gets successful response (200 with requested data)
And I just call this function in before hooks:
before: {
all: [
authenticate('jwt'),
hook => includeBefore(hook),
hook => isAppForbidden(hook) //here, rest is not important
],
find: [],
get: [],
create: [(hook) => {
hook.data.authorId = hook.params.user.id;
}],
update: [],
patch: [],
remove: []
},
the response im expecting to get, looks something like this:

Found the solution... the key was to wrap the content of function in promise... so it now looks like this:
function isAppForbidden(hook) {
return new Promise((resolve, reject) => {
hook.app.services.settings.find({
query: {
$limit: 1,
$sort: {
createdAt: -1
}
}
}).then(res => {
if (hook.params.user.hiddenApps.indexOf('qualitydocs') >= 0 || res.data[0].forbiddenApps.indexOf('qualitydocs') >= 0) {
reject(new errors.NotAuthenticated());
} else {
resolve();
}
})
})
}
and it works as a charm
