[kedrovski]

You can try .toObject() -> jwt.sign(doc.toObject(), jwtSecret);

[NodeJoSe]

@kedrovski or @UNADYNE solution works fine but i suggest you to use: JSON.parse(JSON.stringify(doc)) if your doc object comes from diferent sources, for example:

You could have to pass diferent “doc” objects, one returned from mongoose and another defined by you like this:

doc = { name: 'foo', description: 'bar' }

If you use .toJSON() or .toObject() You will get a “doc.toObject/doc.toJSON is not a function” error with the doc you defined manually.
