I think as the main project is using react-18 and as we just try to update docs-site it's throwing an error

When I tried upgrading react-datepicker dependencies also to v19, it worked in my local

The main project now has support for React 19 so that should be good, but we may have missed a place or 2

I got it to work, and created a pull request.

But it's having typescript related issues. Hence many tests are failing

Yeah saw that as well. Help is welcome in fixing those. There are about 10 checks failing right now.

@martijnrusschen I raised a type fixing PR to your react-19 branch - #5301

Let me know if it needs to be raised against the main branch
