e2e tests fails when rxjs is introduced to project

Expected Behavior

Running e2e tests should open cypress.

Current Behavior

Fails with: You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

Failure Information (for bugs)

I suspect that it is due to some internal configuration of how cypress is being incorporated. I only have dependencies installed I don’t use them and e2e tests won’t run.

Steps to Reproduce

git clone [e-mail]:urosappdev/nx-js-bug.git

1. nx run e2e booking-e2e

Please provide any relevant information about your setup:

• version of Nx used: 8.5.1
• 3rd-party libraries and their versions

 "rxfire": "^3.8.2",
 "rxjs": "^6.5.3",

• and most importantly - a use-case that fails

Running e2e tests fails.

I have an update.

Talked to Ben Lesh and apparently the following fixes it: https://github.com/nrwl/nx/commit/a88ee635781e919779a0bad6ad43e97aa37a3d16

I’ll cut a release today with the fix.

I’m going to close this issue.

Update: it worked once I found out resolutions is a yarn thing and I used yarn install.

@vsavkin The resolutions fix doesn’t work for me. I thought the culprit was redux-observable (the only RxJS related dependency I can think of), but the error still shows up if I remove it then rm -rf node_modules package-lock.json && npm i && npm run affected:e2e.
