After building app with ngx-graph for Prod environment tooltip breaks the app.

Od Dev environtmnt everything works fine. But when i build the app with:

ng build --prod my console is filled with errors and page frezzes.

I tried to remove tooltips from my html graph template but this doesn’t help. Updated my ngx-graph and ngx-charts to the latest version and the error still occurs.

Since the TooltipService and InjectionService are from the dependency ngx-charts and not in ngx-graph itself, I looked over there to search for related issues. I found #975.

The only feasible solution proposed seemed to be here, which is just to revert to earlier versions of ngx-graph and ngx-charts. The versions suggested are:

“@swimlane/ngx-graph”: “4.1.1”, “@swimlane/ngx-charts”: “7.3.0”

However, in my case, this was throwing an error because the BaseChartComponent in this old version of ngx-charts was using Observable.fromEvent (I’m using Angular v7 and rxjs v6.3).

I changed to ngx-graph v5.0.0 and ngx-charts v8.1.0 and it worked in production with AOT. So for those who cannot remove aot or build-optimizer, this may be an option.

I ran into this issue as well. This issue is resolved for me when removing aot from build. It is a better workaround than the hack suggested above, but not a desired one. I wander if the answer here can resolve this case as well.
