AngularJS: How to filter object (Error: [filter:notarray])?

Question

JavaScript

Greetings!
There is a data object for forming a select tag through angular.

{
"78-1":{
"ID":"78-1",
"name":"Group 1: №1",
"buyed":false,
"disable":false
},
...
}

An html object is formed from this template (used controlerAs):

<select ng-model="row.ID" ng-options="row_item.ID as row_item.name disable when row_item.disable for row_item in app.data.rows | filter:rowDisabled" class="form-control"></select>

There is a function in the controller, according to which the select data should be filtered and row_item.disable = true should be set for certain items.

BilCtrl.rowDisabled = function() {
        return function (rows) {
        
            var result = {};
            angular.forEach(rows, function(row, key) {
                row.disable = false;
            
                if( row_item.buyed )
                    row.disable = true;
                    
                for( var i in BilCtrl.rows ){
                    if (!BilCtrl.rows.hasOwnProperty(i))
                        continue
                    
                    if( BilCtrl.rows[i].ID == row.ID )
                        row.disable = true;
                }
                
                result[key] = row;
            });
            
            return result;
        };
    };

But this beauty gives me an error: Error: [filter: notarray]
I still couldn't apply the filter. Can't filters be applied to objects? Only arrays? In the example, they use for the object ...

In general, custom filters are written differently
