Help when building storybook and deploying on Vercel

[alexbjorlig]

I'm pretty new to Storybook, and hope you can help me out here.

I have msw-storybook-addon installed version 1.10.0, working fine running locally on my machine.

When I try to build the storybook with the storybook build command, everything also seems to work on Vercel. However, when I visit the environment I get this error:

[MSW] Failed to register a Service Worker for scope ('https://ui-seven-kappa.vercel.app/') with script ('https://ui-seven-kappa.vercel.app/mockServiceWorker.js'): Service Worker script does not exist at the given path.

Did you forget to run "npx msw init <PUBLIC_DIR>"?

Learn more about creating the Service Worker script: https://mswjs.io/docs/cli/init

I tried adding

"msw": {
  "workerDirectory": "public"
}

But that did not seem to help. On Vercel I'm using the Storybook framework preset, that lists storybook-static as "Output directory".

What is wrong with the above configuration 🧐?
