'MapEditServiceConfig'仅引用类型，但在此处用作值

Question

Not sure why this error is prompting for MapEditServiceConfig , saying MapEditServiceConfig refers to a type , also what do we understand as MapEditServiceConfig {}, as MapEditServiceConfig is a interface, what this bracket says?

export interface MapEditServiceConfig extends AppCredentialsConfig {
    readonly "moderation.authServiceId": string;
    readonly "maphub.mc.endpoint": string;
}

export interface AppConfig
    extends MapDataServiceConfig,
        GeocoderConfig,
        LoginServiceConfig,
        ScbeServiceConfig,
        MapJobServiceConfig,
        TaskProviderServiceConfig,
        YourXYZSpaceServiceConfig {

                       "map.defaultLocation":MapDataModels.MapLocation;
            "app.imageBasePath": string;
        },
        MapEditServiceConfig {}  // Getting the refers to a //type , but use as a value here

Answer 1

In your list of interfaces the AppConfig extends there is this part:

 {
   "map.defaultLocation":MapDataModels.MapLocation;
   "app.imageBasePath": string;
},

that is interpreted by the compiler as the actual definition of the AppConfig interface.

The comma is a syntax error, the compiler expects a declaration.

After that follows a new statement MapEditServiceConfig which is interpreted by the compiler as an literal value.
