Types for form.issues is wrong #14489
Description
Describe the bug
It looks like there's a slight bug in either the typing or the actual value of the issues field within a remote form. The typing coming in looks like
(property) issues: ({
username: RemoteFormIssue[];
} & {
password: RemoteFormIssue[];
}) | null
but when I inspect the value of form.issues it's actually {}. This causes a discrepancy between what Typescript thinks the value can be and what it actually is.
Reproduction
Notice that when the project boots up, the page shows a 500 because of the following error:
TypeError: Cannot read properties of undefined (reading 'at')
at eval (src/routes/+page.svelte:49:101)
at Renderer.child (node_modules/svelte/src/internal/server/renderer.js:122:18)
at Renderer.component (node_modules/svelte/src/internal/server/renderer.js:147:22)
at _page (src/routes/+page.svelte:19:14)
at eval (.svelte-kit/generated/root.svelte:74:7)
at eval (src/routes/+layout.svelte:20:5)
at Renderer.child (node_modules/svelte/src/internal/server/renderer.js:122:18)
at Renderer.component (node_modules/svelte/src/internal/server/renderer.js:147:22)
at _layout (src/routes/+layout.svelte:13:14)
However, if you run npm run check there are no typescript errors. This is because logInForm.issues is actually an empty object ({}) instead of null like typescript expects.
