Find not working

[gerMdz]

Good day:
When making a query of the type

$ document = $ this-> manager-> createQueryBuilder (Physical Document :: class)
-> field ('id') -> equals ($ id)
-> getQuery ()
-> getSingleResult ();

and then

$ clse = get_class ($ document);

I get an error

I can't get an empty element class.
However, if I consult directly at the BD if I obtain data.

Use
Symfony 4.4
"doctrine / mongodb-odm-bundle": "^ 4.1",

MongoDB extension version => 1.6.1
libbson bundled version => 1.15.2

Mongodb V 3.4.13

Hello! First, your issue is not about doctrine/mongodb but about doctrine/mongodb-odm. Second, your post has several formatting issues (code fencing being one) and does not clearly say what the problem is. Last as this is a support question rather than a bug in the library please consider posting a question on https://stackoverflow.com/ and tagging it as doctrine-odm.
