Angular UI Router Transition HookMatchCriteria not working - angularjs

Question

My run block is as follows:
angular.module('app', [...]).run(['$transitions', '$state', 'EmployeeService', ($transitions, $state, EmployeeService) => {
$transitions.onBefore(
{ to: 'app.*' },
() => EmployeeService.checkAuth().then(() => {
console.log("run success");
},
() => {
console.log("run caught");
return $state.target('login');
}),
{priority: 10}
);
}])
And for some reason it executes for states 'app' and 'login' though they don't match 'app.*' match criteria, and thus it brings me to infinite loop when performing the logout. What is the right syntax to specify the match criteria ? I've already looked here:

Edit: Posting routes configurations as requested
Routes for the main module (includes 'app' state which shouldn't fire the auth check):
export default mainPageRoutesConfig;
function mainPageRoutesConfig($stateProvider, $urlRouterProvider, $locationProvider) {
"ngInject";
$locationProvider.html5Mode(true).hashPrefix('!');
$urlRouterProvider.otherwise('/');
$stateProvider
.state('app', {
url: '/',
component: 'main'
})
.state('app.timesheet', {
url: 'timesheet',
component: 'timesheet'
})
.state('app.saveHours', {
url: 'saveTaskHours',
component: 'saveTaskHours',
params: {
timesheet:null
}
})
}
Routes for the employee module (includes 'login' state which shouldn't fire the auth check as well):
export default employeesRoutesConfig;
function employeesRoutesConfig($stateProvider, $urlRouterProvider, $locationProvider) {
"ngInject";
$locationProvider.html5Mode(true).hashPrefix('!');
$urlRouterProvider.otherwise('/');
$stateProvider
.state('login', {
url: 'login',
component: 'login'
})
.state('app.employeesList', {
url: 'employees',
component: 'employeesList'
})
.state('app.saveEmployee', {
url: 'employee/?Id',
component: 'saveEmployee'
})
.state('app.deleteEmployee', {
url: 'employee/:Id',
component: 'deleteEmployee'
})
.state('app.employeePage', {
url: 'profile/:Id',
component: 'employeePage'
})
}

The solution (though not really an answer) was to specify match criteria as a function:
{
to: function(state) {
return state.name !== 'app.login' && state.name !== 'app.error';
}
}
And the full code (after moving to separate file):
export default ($transitions, $state, EmployeeService) => {
$transitions.onBefore(
{
to: function(state) {
return state.name !== 'app.login' && state.name !== 'app.error';
}
},
() => EmployeeService.checkAuth().then(() => {
console.log("run block. Authorization check succeeded");
},
() => {
console.log("run block. Authorization check failed");
return $state.target('app.login');
}),
{priority: 10}
);
}])
