Using middleware to disable Unexpected Server Error server errors sanitization

[remorses]

I would like to keep the error message of some Error classes by using middleware, is this a supported use case?

When I tried the middleware was not able to catch the loader error, instead I still got the usual Unexpected Server Error

const catchErrors: Route.unstable_MiddlewareFunction = async (
    { request },
    next,
) => {
    try {
        return await next()
    } catch (error) {
        console.error('Middleware caught an error:', error)
        throw new Response(error.message, { status: 500 })
    }
}

Does anyone know how to preserver the error message somehow?
