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

Thanks.

Commencez par reproduire le scénario de changement dynamique de module, puis suivez PlotlyComponent.ngOnDestroy et PlotlyService.plotly.purge dans angular-plotly.js. Comparez la manière dont PlotlyViaCDNModule est configuré et chargé dans les deux modules ; le travail est terminé lorsque le changement de contexte ne déclenche plus de purge TypeError.
