We are experiencing an issue when using angular-plotly.js and Angular17 saying that "'PlotlyModule' does not appear to be an NgModule class."

Error

error NG6002: 'PlotlyModule' does not appear to be an NgModule class.

176     PlotlyModule,
        ~~~~~~~~~~~~

  node_modules/angular-plotly.js/lib/plotly.module.d.ts:1:22
    1 export declare class PlotlyModule {
                           ~~~~~~~~~~~~
    This likely means that the library (angular-plotly.js) which declares PlotlyModule is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

app.module.ts

import * as PlotlyJS from 'plotly.js-dist-min';
import { PlotlyModule } from 'angular-plotly.js';
PlotlyModule.plotlyjs = PlotlyJS;

@NgModule({
  declarations: [
    ...,
  ],
  imports: [
    ...,
    PlotlyModule,
    ...,
]
});

Is there something that can be done that will enable this to work?

    Hey, I'm facing the exact same issue while upgrading from Angular 15 to Angular 16. Did you find a solution?
