@vignesh20794 would you mind creating a repo to reproduce this issue? That would be very helpful to debug.

I run into the same issue on this Repo: https://github.com/opensource-challenge/opensource-challenge-client/tree/dependency-updates (branch dependency-updates) somehow the xhr.response is a string which would need to be parsed before accessing...

I debugged this with someone earlier today, and in our case the issue was that some tests were not properly resetting the pretender instance so window.XMLHttpRequest was the FakeRequest object that Pretender installs, which does not respect the responseType property.

Specifically, someone was calling this.server = setupMirage() in their test, but never this.server.shutdown().
