Date: January 24, 2024

SvelteKit is a web development kit. In SvelteKit 2, sending a GET request with a body eg "{}" to a built and previewed/hosted sveltekit app throws "Request with GET/HEAD method cannot have body." and crashes the preview/hosting. After this happens, one must manually restart the app. "TRACE" requests will also cause the app to crash. Prerendered pages and SvelteKit 1 apps are not affected. "@sveltejs/adapter-node" versions 2.1.2, 3.0.3, and 4.0.1 and "@sveltejs/kit" version 2.4.3 contain a patch for this issue.
