not compatible with eslint 9+?

[nullbio]

I think this is because the plugin does not appear to be compatible with eslint 9?

Here's a github issue having the same errors due to version incompatibility, hence why I assume this is the reason:

Confirmed here too

ESLint version 9 deprecated .eslintrc files in favor of what they call "flat configs" which essentially are just javascript objects with a similar but slightly different structure. https://eslint.org/docs/latest/use/configure/configuration-files

If you're trying to use the new config format, it won't work until the extension is updated.

You should be able to do one of the following to get things working:

• Set ESLINT_USE_FLAT_CONFIG=false in a .env file
• Downgrade ESLint to version 8

Wow! I hope it can be supported.
