[Bug] Storybook Deploy Fails with Node Version 14.18.2

[megob56]

Describe the bug

Currently upgrading our repository from node version 12 to version 14.18.2. We are using storybook-deployer version 2.8.7. When I changed the node version to v14.18.2, storybook-deployer fails to deploy.

Steps to reproduce the behavior

1. Use node version 14.18.2
2. Run storybook-deploy command
3. Get error:

internal/fs/utils.js:811
  throw new ERR_INVALID_ARG_TYPE(
  ^

TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of Array
    at Object.writeFileSync (fs.js:1521:5)

Expected behavior

Expected storybook to deploy to github pages

Environment

• OS: iOS
• Node.js version: v14.18.2
• NPM version: v7.21.1

Local Resolution

I was able to resolve the problem locally by following the advice on this stackoverflow page Stackoverflow Link

Changed line 63 in src > build-monorepo-index.js to fs.writeFileSync(path.join(outputDir, 'index.html'), index.toString()); within the storybook-deployer package and achieved success outcome.
