Could not get the request store (Async SSR bug)

[sillvva]

Describe the bug

I'm trying the async SSR without the <svelte:boundary>. In my remote function, it is throwing this error.

file:///Users/sillvva/Projects/ddal-svelte/node_modules/.pnpm/@sveltejs+kit@2.42.1_@sveltejs+vite-plugin-svelte@6.2.0_svelte@5.39.1_vite@7.1.5_@types_50b82b04ebe0765b72e2573be5ec4697/node_modules/@sveltejs/kit/src/exports/internal/event.js:48
                throw new Error('Could not get the request store. This is an internal error.');
                      ^

Severity

annoyance

Per the team, this is due to Kit not supporting Async SSR yet. Closing issue as it should work once that is added.

Can I somehow opt out of SSR for this to continue with testing / preparation until the feature is available? 🤩

[sillvva]

Just continue using <svelte:boundary> tags with pending snippets wherever you use remote functions for now. Once the Kit implementation is available, then you can remove them.

Today we updated to @svelte/kit@2.43.1, and started getting this same error.
We are not using any of the new remote functions, and all runs fine in 2.42.x

MRE showing the above still occurring on the latest versions of svelte and @sveltejs/kit

I see this happeneing only in Stackblitz - is it happening for you locally aswell? It should only happening if your environment doesn't support AsyncLocalStorage
