访问 Typescript-ES5 或节点错误消息

Question

I have an error handler. I don't know if it is Node or Typescript-ES5 Error object. When I inspect in the console, I have the following

{…}
error: Object { message: "message that I want to get" }
headers: Object { normalizedNames: Map(0), lazyUpdate: null, lazyInit: lazyInit()
 }
message: "Http failure response for http://localhost:4200/someEnpointUrl: 400 Bad Request"
name: "HttpErrorResponse"
ok: false
status: 400
statusText: "Bad Request"
url: "http://localhost:4200/someEnpointUrl"
<prototype>: Object { … }

Inspecting the Error object the only information I can get is error.name and error.message, but in my case I get error.message = "Http failure response for http://localhost:4200/someEnpointUrl: 400 Bad Request" and error.name = HttpErrorResponse

On the back-end, the error is coming from

throw new ControllerException(HttpStatus.BAD_REQUEST, "message that I want to get");

How can I get the error message on the front end (error: Object { message: "message that I want to get" }) The editor cannot get this object property?

I found the solution: I created a custom error

export class ExtendedError extends Error{

  public error!: { message: string }
  constructor(m: string) {
    super(m);
  }
}

and can get error.error.message The discussion is closed
