These are really hard to spot. Maybe I should have used an automated tool 🫠

Thanks for fixing it!

Year, it's no surprise to miss one in the middle of logic like this 😄

I'm wondering why ESLint still cannot detect these refs even though we successfully upgraded ESLint configs by #2651

I also tried adding a specific rule for this (https://eslint.vuejs.org/rules/no-ref-as-operand.html) but it still fails to detect the usage without .value:

https://github.com/elk-zone/elk/blob/9da77637b22d4ce294449f4ee6540d97645b2d8a/eslint.config.js

...
export default await antfu(
  {
    unocss: false,
    vue: {
      overrides: {
        'vue/no-restricted-syntax': ['error', {
          selector: 'VElement[name=\'a\']',
          message: 'Use NuxtLink instead.',
        }],
+       'vue/no-ref-as-operand': 'error',
      },
    },
...

@shuuji3 L62 needs also .value

[shuuji3]

@userquin @patak-dev Yes, that's another one👍🏻 I also found a temporary workaround to enable this rule and found other ones too. I will send a PR to fix them together today.

I wrote the workaround here: #2678
