EJS-Gantt freeze the browser in production

Question

Dear supporters,I'm having a runtime error while using ejs-gantt and don't know how to resolve it. When using my localhost, everything working fine, the gantt still displays and no exception catched. But in my live product, the browser is freeze every time I open the ejs-gantt, and the exception error show "Error: NullInjectorError: No provider for GanttSort". I'm using the same datasource for both localhost and live product. Can you help me with this.Thank you!

Hi Lam, 
 
We checked the Gantt sample in production mode, but we are unable to reproduce the issue. 
Please find the tested sample link. 
Sample – https://www.syncfusion.com/downloads/support/directtrac/general/ze/sample-417422385 
Please refer the below stack-overflow link. 
https://stackoverflow.com/questions/53781727/angular-7-nullinjectorerror-no-provider-for-pagerservice 
 
In Gantt, we inject Sort module as like below example in app.module.ts 




//... 
import { GanttModule, SortService } from '@syncfusion/ej2-angular-gantt'; 
@NgModule({ 
  //... 
  providers: [SortService], 
}) 
 
Please ensure, whether you have injected the Sort module as shown in above tabulation. 
If the issue still persists, please share us your angular-cli version and please modify our provided sample, so that it will be very helpful to check in our end.
