`isomorphic-dompurify` with Angular 18 SSR runtime error: Cannot convert undefined or null to...

I installed isomorphic-dompurify ^2.15.0 to my Angular 18 SSR application. It builds successfully with the standard DomPurify code, such as:

import DOMPurify from "isomorphic-dompurify";
DOMPurify.sanitize(dirtyHtml);


But at runtime, you will get the following error:
