Ng-zorro-antd: StaticInjectorError(AppModule)[CdkConnectedOverlay -> Overlay]

[dylanvdmerwe]

Reproduction link

https://stackblitz.com/edit/ng-zorro-antd-start-hspl9z?file=package.json

Steps to reproduce

Build works perfectly when doing a normal ng serve. Doing a --prod build compiles correctly. However browsing to the site in a browser that has been built in --prod mode, does not work.

I see that ng-zorro has a dependency on @angular/cdk. I also need to use the cdk dep in my own project so I need to add a reference to the project. As 7.5.1 uses cdk 7.3.7 as a dependency (from lock file), I added this version to my project.

I do not know what could be causing this.

What is expected?

Running an angular site in --prod mode should work correctly. Currently I have a site that does not work properly now.

What is actually happening?

In the browser, there are many errors like this:

ERROR Error: StaticInjectorError[t -> t]: 
  StaticInjectorError(Platform: core)[t -> t]: 
    NullInjectorError: No provider for t!

If you disable the terser step of a --prod build the error looks as follows:

main.69af81de163627084b5e.js:28873 ERROR Error: StaticInjectorError(AppModule)[CdkConnectedOverlay -> Overlay]:
 StaticInjectorError(Platform: core)[CdkConnectedOverlay -> Overlay]:
   NullInjectorError: No provider for Overlay!

| Environment | Info |
|---|---|
| ng-zorro-antd | 7.5.1 |
| Browser | Chrome |

Note I cannot update to angular 8 and the latest version of ng-zorro just yet.

Fixed. In app.module.ts these modules need to be included:
ScrollingModule, DragDropModule

@dylanvdmerwe Doesn't work for me. Does it work for you in angular 8.1.1 and ng-zorro-antd 8.1.0?

[dylanvdmerwe]

I have not tried NG 8 yet. Probably some other module required?

This was my problem https://github.com/NG-ZORRO/ng-zorro-antd/issues/3713#issuecomment-513933229

Adding CdkConnectedOverlay to providers list of each module you use may fix this problem. It works for me.

@amiram is right! I had the same problem. I have angularCDK in package.json and ngZorro is having another version as a dependency and this causes issues always

[thinkdj]

For anyone who's still stuck with these: I spent ~6 hours behind this. Got it working via some hacky methods (removing/replacing zorro's dependency version, matching my project's CDK with zorro's ... )
Finally, upgrading angular + cdk + zorro to the latest (8.x/9.x) seemed to be the best solution. The time invested in this migration was very well worth it on multiple levels. Zero hacks, zero errors now.
