Resolver Emitting Error ` ERROR Error: “[object Object]” `

Question

I\'m having a problem with regards of implementing a resolver on my routes as it has no issue until I include InitialDataResolver on my routing module.

I have found solution for detailed error working in firefox. Its based on defining custom error handler and inspecting error properties yourself. After these steps, the errors were displayed properly, no need to switch to chrome.

1. Define custom error handler class:

import { ErrorHandler } from '@angular/core'

export class MyErrorHandler implements ErrorHandler {

    handleError(error: any) {
        // console.error(Object.getOwnPropertyNames(error))
        // Object.getOwnPropertyNames(error).forEach(p => console.error(error[p]))
        console.error(error.fileName, error.lineNumber, ':', error.columnNumber, '\n', error.message, error.rejection)
    }

}

2. Then register it as provider in main component

@NgModule({
    declarations: []
    imports: []
    providers: [{provide: ErrorHandler, useClass: MyErrorHandler}], // <-- register MyErrorHandler
    bootstrap: [RootComponent]
})
export class AppModule { }
