TypeError: PlotlyService.plotly.purge is not a function

Getting this error when switching active submodules

Submodule config:

...
import { PlotlyViaCDNModule } from 'angular-plotly.js';

PlotlyViaCDNModule.setPlotlyVersion('latest');
PlotlyViaCDNModule.setPlotlyBundle('finance');

@NgModule({
  declarations: [
    DcComponent,
    DcChartComponent,
    ...
  ],
  imports: [
    CommonModule,
    DcRoutingModule,
    ...
    PlotlyViaCDNModule,
    ...
  ]
  ...
}
export class DcModule { }

Note that the scenario is that the Plotly Data Card is configured and saved in one module, then dynamically loaded and displayed in another module. The error occurs sometimes when switching contexts (modules). I guess when the second by loading order is first loaded.

Env:

$ npm list angular-plotly.js
...
└── angular-plotly.js@4.0.4 

$ ng version

Bắt đầu bằng cách tái hiện kịch bản chuyển đổi module động, sau đó truy vết PlotlyComponent.ngOnDestroy và PlotlyService.plotly.purge trong angular-plotly.js. So sánh cách PlotlyViaCDNModule được cấu hình và tải trong hai module; hoàn tất khi việc chuyển đổi ngữ cảnh không còn gây ra purge TypeError.
