FWIW - I can confirm this as well. Had the same experience.

• Node 22.1.0
• eslint-plugin-solid version 0.14.3
• eslint 9.9.1

When I drop back to eslint-plugin-solid version 0.14.2, no issue.

@jcarpe Did you mean 0.14.2?

Apologies - updated the comment, but yes. When dropping back to 0.14.2, no problem.

I think this might be an incompatibility with using compat.extends. Extending 'plugin:solid/typescript' should already define the solid plugin, so you may need to remove it from your plugins object:

    plugins: {
        '@typescript-eslint': typescriptEslint,
-       solid,
    },

    languageOptions: {

Does this resolve your issue?
