Companion to #16186 — right now we return an empty array when undefined is more helpful. Small/edgey enough that I didn't think it warranted a test


Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

  • It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
  • This message body should clearly illustrate what problems it solves.
  • Ideally, include a test that fails without this PR but passes with it.

Tests

  • Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

  • If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

Edits

  • Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.

Comment thread packages/kit/src/runtime/form-utils.js Outdated
Co-authored-by: Tee Ming <chewteeming01@gmail.com>
Comment thread packages/kit/src/runtime/form-utils.js Outdated
…t breaks the entire module.

This commit fixes the issue reported at packages/kit/src/runtime/form-utils.js:697

## Bug

In `packages/kit/src/runtime/form-utils.js:697` the line read:

```js
return issues?.length ? issues : undefined);
```

There is an unbalanced closing parenthesis with no matching opening paren. This produces a parse-time `SyntaxError`, confirmed by `node --check`:

```
SyntaxError: Unexpected token ')'
```

A parse error breaks the **entire module**, so any build or import of `form-utils.js` fails.

### How it happened
The previous code was `return issues && (issues.length > 0 ? issues : undefined);`, where the `)` matched the `(` after `&&`. A committed GitHub suggestion replaced the expression with `issues?.length ? issues : undefined` but left the trailing `)` in place, leaving it unbalanced.

## Fix

Removed the stray `)`:

```js
return issues?.length ? issues : undefined;
```

After the change `node --check packages/kit/src/runtime/form-utils.js` passes. The behavior is preserved: the optional-chaining `issues?.length` correctly handles the `undefined`/`null` case that the previous `issues && ...` guard covered.
