I am having an issue with error.tsx file with error handling.
Once I added that special file, I started getting this error.
TypeError: Cannot read properties of null (reading '_pendingVisibility')
And lots of warning messages with this.
Warning: Unexpected Fiber popped.

And when I click the link (or button to navigate to other page), It showed white screen with the same route. (Does not go to the route it has to be)
This time, it showed these errors.
The above error occurred in the <ErrorBoundaryHandler> component:
Uncaught Error: Unexpected Suspense handler tag (undefined). This is a bug in React.
fetch-server-response.js:64 GET http://localhost:3000/collection/2VLjompcdUoCM0PwgE8kHb9Q79M?_rsc=acgkz net::ERR_CONNECTION_REFUSED
Failed to fetch RSC payload. Falling back to browser navigation. TypeError: Failed to fetch
Do you have any idea on that?

P.S: This happens only on SSR routes. It works fine on Client Side rendering routes.
