API routes not recieving body when build with netlify-adapter and deployed to netlify

[chiptopher]

Describe the bug
I've got a SvelteKit application set up on netlify using the netlify-adapter. Locally everything works fine. I can make a POST request no problem. However, when I push it up to netlify I get the following error:

ERROR  TypeError: Cannot destructure property 'name' of 'req.body' as it is undefined.

specifically on this line of code:

    const { name } = req.body;

A console.log of the entire request reveals that the request netlify receives has no body at all.

Looking at the source for the netlify-adapter, I think this line of code might be the culprit.

Expected behavior
I would expect the body of my API request to be appropriately forwarded to the render netlify function.

• Your adapter: netlify

Severity
I don't think it's a huge deal. I could write out my API routes as raw netlify functions, or, if I wanted to stay in SvelteKit, I could probably turn my body into request query parameters since it looks like they're being forwarded to the renderer, so I have a path forward if I want to keep using netlify. I could probably also try a different host.

This appears to have been resolved as a part of #1109. Thanks!
