I may need a repo example, I think that maybe this plugin is conflicting with some other you have installed

I'm getting this, too, using Create React App. I'll likely have an example later today, or this week. You might be able to repro by creating a new CRA, then npx sb init, and then add the rule to main.js...?

I'll give it a shot!

FWIW, while there's an investigation: this solved the issue for me.

I am also using the CRA and also the following addons addons: [ "storybook-css-modules-preset", "@storybook/addon-links", "@storybook/addon-essentials", "@storybook/preset-create-react-app", "@storybook/addon-a11y", ],
Nothing special else. FYI, I am not using SCSS

@Negan1911 I Sorry, I was not attentive. CSS modules are working with the storybook and RCA under the hood already because of RCA webpack configuration. No need of additional addons. You may close the issue
