"vue/no-deprecated-slot-attribute" doesn't accept any properties

Checklist

• I have tried restarting my IDE and the issue persists.
• I have read the FAQ and my problem is not listed.

Tell us about your environment

• ESLint version: 9.31.0
• eslint-plugin-vue version: 10.3.0
• Vue version: 3.5.16
• Node version: 22.13.0
• Operating System: MacOS (issue also is present on Windows 11)

Please show your full configuration:
eslint.config.ts

import { globalIgnores } from 'eslint/config';
import { defineConfigWithVueTs, vueTsConfigs } from '@vue/eslint-config-typescript';
import pluginVue from 'eslint-plugin-vue';
import skipFormatting from '@vue/eslint-config-prettier/skip-formatting';

export default defineConfigWithVueTs(
  {
    name: 'app/files-to-lint',
    files: ['**/*.{ts,mts,tsx,vue}'],
  },

  globalIgnores(['**/dist/**', '**/dist-ssr/**', '**/coverage/**']),

  pluginVue.configs['flat/essential'],
  vueTsConfigs.recommended,
  skipFormatting,
  {
    rules: {
      'vue/no-deprecated-slot-attribute': [
        'error',
        {
          ignore: [/^shine-/], // also doesn't work when using a string
          ignoreParents: [/^shine-/],
        },
      ],
    },
  },
);

What did you do?

<shine-dialog>
  <div slot="header-text">{{ actionTextDialogHeader }}</div>
</shine-dialog>

What did you expect to happen?
ESLint should run and allow the usage of the native slot attribute with all components starting with shine- and all its descendents.

What actually happened?
As per https://eslint.vuejs.org/rules/no-deprecated-slot-attribute, the rule accepts props, but an error occurs when running eslint:

Oops! Something went wrong! :(

ESLint: 9.31.0

Error: Key "rules": Key "vue/no-deprecated-slot-attribute":
Value {"ignore":["/^shine-/"],"ignoreParents":["/^shine-/"]} should NOT have additional properties.
Unexpected property "ignoreParents". Expected properties: "ignore".

Repository to reproduce this issue
git clone, npm i, npm run dev and npx eslint ./src/App.vue on this repo:

ignoreParents was added in 9140c63

It's unreleased for now. Just wait for the release.

Thanks for the clarification!
We were a little confused that it was already mentioned in the documentation. But then we'll wait.
I'll close the issue.

@MaxGeldner This is now available in v10.4.0.

It seems using RegExp doesn't work, whereas the documentation seems to allow it even with version 10.5.0.

"ignoreParents" (string[]) An array of tags or regular expression patterns (e.g. /^custom-/) for parents that ignore these rules. This option is especially useful for Web-Components. Default is empty.

When I use this config,

'vue/no-deprecated-slot-attribute': ['error', { ignoreParents: [/^Prefix/] }]

I get this error:

> eslint --max-warnings=0 --cache

ESLint: 9.35.0

Error: Key "rules": Key "vue/no-deprecated-slot-attribute":
        Value {} should be string.

try "/^Prefix/" instead of /^Prefix/

Thank you, it is working.

I was not expecting this behavior when reading the documentation. Real RegExp should be allowed, IMHO.
