Multiple versions of @sanity/generate-help-url from block-content-to-hyperscript

This is a dependency conflict issue that's actually not a problem with your code, but rather with an outdated transitive dependency. Here's what's happening:

The @sanity/block-content-to-hyperscript package is deprecated and has been replaced by modern alternatives. Even though you're not directly using it in your project, some older Sanity package might still have it as a dependency, which is causing the version conflict with @sanity/generate-help-url.

Solution

The best approach is to migrate away from the deprecated packages. According to the official Sanity documentation, here are the modern replacements:

For rendering Portable Text:

1. For HTML: Use @portabletext/to-html instead of @sanity/block-content-to-html or @sanity/block-content-to-hyperscript

2. For React: Use @portabletext/react instead of @sanity/block-content-to-react

3. For other frameworks: There are modern packages for Vue, Svelte, React Native, and Astro

Immediate workarounds:

If you can't migrate immediately, try these:

1. Use npm resolutions (in package.json):

{
  "resolutions": {
    "@sanity/generate-help-url": "^3.0.0"
  }
}

2. Use yarn resolutions or npm overrides to force a single version

3. Clear your lock file and reinstall:

rm -rf node_modules package-lock.json
npm install

Long-term fix:

Check which Sanity packages you're using and update them to their latest versions. The core Sanity packages have been updated to remove dependencies on these deprecated packages. Run:

npm outdated

Then update your Sanity packages:

npm update @sanity/client sanity

The block-content-to-hyperscript package is no longer maintained by Sanity, so this isn't something that will be "fixed in the core Sanity package" - it's been replaced by the modern Portable Text tooling mentioned above.
