RxJs mismatch issues in DataPersistance keep coming back

[evtk]

Expected Behavior

I can run an upgrade of NX with npm run update, without getting issues with dataPersistance.

Current Behavior

I have spent a lot of time to get the issues I had with RxJS version mismatch solved. See this topic: #1416 (comment).

Now it has been a while since I had the time to upgrade NX. So coming from "@nrwl/angular": "8.6.0" I am updating to "@nrwl/angular": "8.12.1". But as soon this upgrade is done, I get the same RxJS related errors.

Failure Information (for bugs)

My RxJS version is pinned to 6.5.3. After running the update I get these types of errors:

Type 'Observable<MyAction>' is not assignable to type 'void | Action | Observable<Action>'. Type 'Observable<MyAction>' is not assignable to type 'Observable<Action>'. Types of property 'source' are incompatible. Type 'import("/Users/evtk/Documents/git/my.repo/client/angular/node_modules/rxjs/internal/Observable").Observable<any>' is not assignable to type 'import("/Users/evtk/Documents/git/my.repo/client/angular/node_modules/@nrwl/angular/node_modules/rxjs/internal/Observable").Observable<any>'.

So then I decided to downgrade to the 6.4.0 version of RxJS. This is unwanted, because I have another package explicitly asking for 6.5.3, but just to make sure. After downgrading to RxJS 6.4.0 I have checked my package-lock file and it doesn't contain any references to RxJS 6.5.3. anymore. Now I can build my app, but as soon as I serve it, I get these type of errors again:

... dispatched an invalid action: {"_isScalar":false,"source"

Steps to Reproduce

I can't share my repo because it contains corporate code, but here is my package.json after just running the npm update. I feel that there should be no need to downgrade RxJS.

I experience the exact same issue (@nrwl/angular version 8.12.2):
After downgrading rxjs to 6.4.0 I get this:

... dispatched an invalid action: {"_isScalar":false,"source"

[vsavkin]

It's a common problem with having more than one version of RxJS. Could you try the following: https://github.com/nrwl/nx/issues/2458

[evtk]

@vsavkin your fix with npm resolutions worked. After updating to NX 9, it seems it works even without it. I'll close this one up.
