How to update a field in an array of objects in MongoDB?

Question

MongoDB

When using the $in operator on an array of objects, for some reason it only updates the first object.
Document structure:

{
    _id: 'ID document',
    comments: [{
        _id: ObjectId("597cea075b116f0e9e2cca55"),
        closed: false,
        text: "string"
    }, {
        _id: ObjectId("597ce96f5b116f0e9e2cca54"),
        closed: false,
        text: "string"
    }]
}

I pass an array of identifiers to the request ['597cea075b116f0e9e2cca55', '597ce96f5b116f0e9e2cca54']
Here is the request itself

Posts
    .update({
        'comments._id': {
            $in: commentsIds
        }
    },{
        $set: {
            'comments.$.closed': true
        }    
    }, (e) => {
        console.log(e);
        process.exit();
});

With such a request, the first ID from the array is taken and the comments.closed field is changed, other IDs are not affected for some reason. There are no errors. How to be? Change everything in a cycle?
