How to prevent caching of errors when using headers() export?

[mbrowne]

Hi, I noticed that if an error is thrown by my loader function (or any helper function it calls), via throw new Error(), react-router will still send whatever cache-control headers I'm returning in my exported headers function. I know that I can return headers from my loader and access them via loaderHeaders, but I don't want to have to rely on my loader in that way if I can avoid it, because I always want the cache-control headers to be the same for this loader except when there's an error. Also, I want to set some default headers in a reusable way in a few of my loaders, and having to always use loaderHeaders seems brittle.

Is there any solution for this using existing react-router features? I checked out the HeadersArgs passed to the headers function, but at least in my case all of those arguments are exactly the same regardless of whether it's an error response or a 200 response.
