Raised when a successful HTTP response could not be decoded into the
caller's expected shape — JSON parse failure, a decode: Decoder<T> that
returned Left(DecoderError), a throwing decodeUnsafe / validate, etc.
In practice cause is a DecoderError (when produced by the decode
path) or an Error (otherwise) — but the field is typed unknown for
back-compat with the 1.0.x runtime.
