Enum ErrorOrigin 

pub enum ErrorOrigin {
    Parse,
    Internal,
}

Which upstream throw an error corresponds to, and therefore which body a client sees.

handleParseErrors branches on the type of the thrown value rather than on its code (middlewares.js:596-646). A Parse.Error renders its own message; anything else renders a fixed one and the detail goes only to the log. So the same detail is a disclosure or not depending on which of the two it travelled in, and the code alone cannot tell them apart: upstream throws Parse.Error(INTERNAL_SERVER_ERROR, ...) deliberately in several places (Auth.js:195, DatabaseController.js:1590-1595) and those keep their messages.

No Default impl, deliberately. A forgotten field would select the disclosing variant, which is the failure this enum exists to prevent. Every value is chosen by a constructor.

Variants

Parse

A Parse.Error. The message is wire-visible.

Internal

A bare Error upstream. The message is server-side detail and never reaches a client.
