# How to change function to export function for decorator?

I have an angular project where I am importing a module using the following code in app.module.ts:

@NgModule({
imports: [
...,
NgxEchartsModule.forRoot({
echarts: () => import('echarts')
}),
],
})


But when I am trying to build the project into serverless, I am getting the following regarding the above import and asking me to change it to export function so that it can be supported by decarator. How do I do that? I tried different export approaches but it is not working.

ERROR in src/app/app.module.ts(107,16): Error during template compile of 'ɵ0'
Function expressions are not supported in decorators
Consider changing the function expression into an exported function.


For reference, I am trying to import ngx-echarts into angular project. https://www.npmjs.com/package/ngx-echarts

Thank you for any help.
