No response

Describe the Bug

Im trying to npm run preview my app with server actions in the client script tag. I have trailingSlash: "always" seted in my config and the problem is when i try to invoke action, node createStaticHandler doesnt pass any url without / at the end and returning 301 for this request.

Request examples with trailingSlash: "always":

If i remove trailingSlash: "always" actions works fine

Request examples without trailingSlash: "always":

What's the expected result?

Not to get this behavior
