Internal Server Error

Returned for any database or infrastructure failure not classifiable as one of the typed variants. The detail field is always the constant literal "internal server error" — no internal path fragment, crate name, or underlying-library substring is ever leaked (security-by-construction).

Example RFC 7807 body

{
  "type":   "https://ferra.rs/errors/internal",
  "title":  "Internal Server Error",
  "status": 500,
  "detail": "internal server error"
}
