Why is req.acl sometimes not available?

Question

Node.js

I use mean.io for the project, during installation the system works stably, but acl in my module is sometimes not available. But the articles reference module is always available.
Here is mine where it happens:

var hasPermissions = function(req, res, next) {

  req.body.permissions = req.body.permissions || ['authenticated'];

  for (var i = 0; i < req.body.permissions.length; i++) {
    var permission = req.body.permissions[i];
    if(typeof(req.acl) === 'undefined'){
      console.log('req.acl: ', req.acl);
    }
    
    if (req.acl.user.allowed.indexOf(permission) === -1) {
      return res.status(401).send('User not allowed to assign ' + permission + ' permission.');
    }
  }

  next();
};

The function call happens here:

...
app.route('/api/' + name + e + 's')
      .get(controller.all)
      .post(auth.requiresLogin, hasPermissions, controller.create);
...

Error in console:

req.acl:  undefined

Friends, tell me, what could be the problem?
Why is sometimes the user in rec.acl available and sometimes not?
This problem happens when writing data to the database. For example, when creating a new document...
Restarting the server helps to recover, sometimes just restarting is enough, and sometimes a full collection using the gulp command.
