I receive the following error while running my e2e tests after upgrading from Angular12 to Angular13. How do I start to track down the source of this error?

I can compile with 'ng build'.

 /opt/wdio/node_modules/@angular-devkit/core/node_modules/rxjs/internal/util/hostReportError.js:4
     setTimeout(function () { throw err; }, 0);
                              ^
