Say I have a req.body like so

{ user_info: { custom: { '63': 'aaaaaaaa' }, email: 'test@test.com', name: 'A Name', } }

I want run body().escape() on it all but when I do I get custom as '[object Object]'.

The thing to note here is I will not know what keys are inside custom and also I will not know what keys are inside user_info. The fields that come through are completely unknown. So I have tried [body('user_info.custom.*').escape(), body('user_info.*).escape()] but this still return custom as [object Object]. I really just want to escape every key that comes through. But is this possible when I dont know the key names and it is nested like this?
