While running in node environment, fetch-intercept uses whatwg-fetch pollyfill but since it is not included in dependencies, it is not available and hence generates this error.

https://github.com/werk85/fetch-intercept/blob/develop/src/attach.js#L36

As a workaround, adding whatwg-fetch@3.2.0 as a dev dependency in the main project worked for me.
