I just migrated my project under angular-cli and I'm getting this error when I start it:
ERROR in Error encountered resolving symbol values statically. Function calls are not supported. Consider replacing the function or lambda with a reference to an exported function (position 63:45 in the original .ts file), resolving symbol AppModule in C:/Data/Private/Innovation/EV/ev-dashboard/src/app/app.module.ts
Which corresponds to the APP_INITIALIZER below in app.module.ts:
...
providers: [ // expose our Services and Providers into Angular's dependency injection
APP_PROVIDERS,
ConfigService,
{ provide: APP_INITIALIZER, useFactory: (config: ConfigService) => () => config.load(), deps: [ConfigService], multi: true }
...
What is funny is that when I comment this line, it starts well and uncomment it afterward which triggers a compilation without error this time!!!
Do you have an idea?
Thanks, Serge.
You need to extract function like:
export function configFactory(config: ConfigService) {
return () => config.load()
}
...
providers: [{
provide: APP_INITIALIZER,
useFactory: configFactory,
deps: [ConfigService],
multi: true
}
