v7.2.0 vite custom server input is ignored

[depsimon]

I'm using React Router as a...

framework

Reproduction

Go to https://vercel-hono-rr7.vercel.app/ and open the console.

The context output does not come from the custom server.

System Info

I don't think it's relevant as it only occurs in Vercel (and perhaps other platforms).

Used Package Manager

npm

Expected Behavior

It should use the custom server when specified and return the VALUE_FROM_HONO specified in the server's context.

Actual Behavior

The custom server input is ignored and the default server is used.

Having same problem. Any solutions? :(

@PeraSite It seems it'll be fixed with #13107

Oh I see. Thanks!

I've just merged #13107 that fixes this issue which will be out in the next release.

I've published this fix as 0.0.0-experimental-58439e382 if you want to try it out in the meantime and report back.

Thanks @markdalgleish, updated my reproduction to use the experimental version and it works!
