@SukkaW is it the right fix though?

I'm actually not using any recommended presets with different plugins (e.g. import plugin). They don't give any errors if I don't set languageOptions manually and just use default ones (ecmaVersion, sourceType, parserOptions, etc)

There must be some way the plugin to just use default ones from eslint 🤔

The PR not only changes the default config presets but also changes how the sourceType is read from the eslint context.

@SukkaW perfect! Sorry I've somehow missed the second part of update 😅 Will happily switch from import to import-x once the error is resolved. Thank you!

@vladshcherbin In the meantime, you could try out import-x first, and patch your node_modules with the changes from this PR, to validate if my PR has fixed the issue or not! If the issue still persists, the reproduction would be much appreciated!

@SukkaW I've tried by patching - the error is still there.

I've also added console.log to current/this version in utils/source-type function to double check and it didn't show anything - I believe it's not even executed in my sample reproduction for some reason. The file is loaded though

Current 4.4.2 reproduction recording

reproduction is the same - https://github.com/vladshcherbin/eslint-import

@SukkaW The rule which gives the error is namespace - sourceType function is not used there. If I turn off this rule - the error is gone ✨
