Clustering markers on the server, react-leaflet?

Question

JavaScript

Good afternoon! I beg you to help!
Please explain how to make the MarkerClusterGroup component for react-leaflet work with server side rendering ?
For the map itself I use react-leaflet-universal, but it doesn't work for clustering.
I try to do it like this

let MarkerClusterGroup;

...

componentDidMount() {
    MarkerClusterGroup = require('react-leaflet-markerclusterr');
  }

Gives errors

warning.js: 33 Warning: React.createElement: type is invalid - expected a string (for built-in components) or a class / function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports

.
I do not understand what to do with this
I will be grateful for any help!
