unknown type for the error in retry function. They also reccomend to perform a runtime check for the error. I'm kinda stuck as I don't lnow how to retrieve the error code from the error in retry function.const trpcError = getTRPCErrorFromUnknown(error) and then getHTTPStatusCodeFromError(trpcError) but the HTTP code returned by helper is 500 instead of 404 visible in JSON.
