Proper way to handle an undefined loader or action

[Jotenges]

Hi, when I have a route that only defines an action e.g. an api only route, how do properly respond with a 404 to GET requests?
I could define a loader that returns the 404, but I was wondering if there's also a way to override the default error raising logic to just respond with a 404 when an action only route received a GET. The only way I see of doing this is by performing a regex match on the error message in handleError in entry.server and returning a 404 if it matches but did not provide a loader for route.

That's an edge case that Remix doesn't handle. I would just export a loader that returns 404.

So it's not possible to detect that handleError is because of non existent loader / action?
