subscribeSpyTo is causing the ''ERROR TypeError: You provided 'undefined' where a stream was expected'' with the RxJS 7 upgrade

[dean-g]

I am getting the following error with the subscribeSpyTo import with the RxJS 7

import { subscribeSpyTo } from '@hirez_io/observer-spy';

      ERROR TypeError: You provided 'undefined' where a stream was expected. You can provide an Observable, Promise, ReadableStream, Array, AsyncIterable, or Iterable.

ERROR TypeError: You provided 'undefined' where a stream was expected. You can provide an Observable, Promise, ReadableStream, Array, AsyncIterable, or Iterable.
          at Object.createInvalidObservableTypeError (/node_modules/rxjs/src/internal/util/throwUnobservableError.ts:7:10)

Can you please advise on this?

Please share your Typescript version and tsconfig.json content so I'll be able to reproduce

Plus the full stack trace (at least the parts that belong to observer-spy) will also help

Thanks
