useFetcher not working for routes that has runtime nodejs

[joeykamsteeg]

I have encountered an issue while using useFetcher in Remix. When utilizing useFetcher for a route configured to run on the Edge Runtime, the route is successfully called. However, when the route is set to run on the nodejs runtime, useFetcher returns a 404 Not Found error.

Can you put together a reproduction repo so that we can take a closer look?

@TooTallNate Sure, I'm on it!

I have made a reproduction repo and running on Vercel, their is a strange twist. In my personal project the node function is not working with useFetcher but in this reproduction repo the Edge function is not working 😅 but the issue is the same.

Extra information: If you try to press the buttons on the live version, you see that only the NodeJS action is popup up in the Network in the inspector. I'm not sure if this is related to 'Single Fetch'

I have setup a new branch without singleFetch and it seems an issue while using Single Fetch
