Improved CORS error handling and authentication fixes

Published: October 15, 2025

v2.3.0

This release improves the developer experience when encountering CORS errors and fixes an authentication issue that previously cleared custom hash parameters during login.

✨ Highlights

Streamlined CORS troubleshooting

When a CORS error occurs, the SDK now presents a direct link to your project's CORS settings in Sanity Manage.

🐛 Notable bugfixes and improvements

  • Authentication: Fixed an issue where the authentication flow cleared all hash parameters from the URL. Custom hash parameters are now preserved during login.
  • TypeScript: Changed ValidProjection to a string type for improved developer experience.
  • Error messaging: Improved styling for error messages.
  • Dependencies: Updated @sanity/client to version 7.12.0.
