Error Page load function doesn't respect redirect during SSR #5669
Description
Describe the bug
If an error page's load function returns a result with the redirect property set, the redirect is honored during client side navigation, but not during SSR.
Reproduction
git clone git@github.com:moatra/svelte_error_redirect.git cd svelte_error_redirect npm install npm run dev Working: Client side navigation
Load http://localhost:5173 in a browser, and click on the the "dashboard" link. The client will eventually land on /login?from=/dashboard due to the dashboard endpoint returning a 401 and the error page redirecting to the login page.
Not working: Server side rendering
Load http://localhost:5173/dashboard in a new browser tab. The browser will get the Error Page html response instead of being redirected to /login?from=/dashboard
Logs
Logging the error that the `__error.svelte` load function receives: Error: Failed to load data at load_shadow_data (file:///home/thomas/Projects/svelte_repros/error_redirect/.svelte-kit/runtime/server/index.js:2705:18) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async load_node (file:///home/thomas/Projects/svelte_repros/error_redirect/.svelte-kit/runtime/server/index.js:2279:5) at async respond$1 (file:///home/thomas/Projects/svelte_repros/error_redirect/.svelte-kit/runtime/server/index.js:2980:15) at async resolve (file:///home/thomas/Projects/svelte_repros/error_redirect/.svelte-kit/runtime/server/index.js:3442:11) at async respond (file:///home/thomas/Projects/svelte_repros/error_redirect/.svelte-kit/runtime/server/index.js:3386:20) at async file:///home/thomas/Projects/svelte_repros/error_redirect/node_modules/@sveltejs/kit/dist/vite.js:2377:22 I believe that's expected due to `dasbhoard.js` always returning a 401 status.System Info
