Cannot read properties of undefined (reading 'spyCallbacks')

[mertohancan]

We are experiencing a runtime error when using the React-scroll library in our Next.js application during server-side rendering

undefined is not an object (evaluating 'c.scrollSpyContainers[c.scrollSpyContainers.indexOf(e)].spyCallbacks')

The error is reported in Sentry, I couldn't repeat it when I tried.

As a reference, as a workaround I applied a patch that simply returns when
scrollSpy.scrollSpyContainers.indexOf(scrollSpyContainer) === -1,
and this has temporarily resolved the issue.
