Store log and send it to slack

I need to store errors in the logs table. If I understood correctly, I should write a report for this in Handler.ts

This is my Handlet.ts

export default class ExceptionHandler extends HttpExceptionHandler {
  constructor() {
    super(Logger)
  }

  public async handle(error: any, ctx: HttpContextContract) {
    console.log(error.messages)
    await Log.create({
      type: 'menus.store', // if we get error in menu store function
      message: error.messages,
    })

    return super.handle(error, ctx)
  }
}

I have two problems. how can I know in which method error I get? to add it to type in log creation. The second question is that I get the same error that am getting in insomnia when testing. for example:

{"errors":[{"rule":"number","field":"menuId","message":"number validation failed on menuId"},{"rule":"exists","field":"menuId","message":"exists validation failed on menuId"}]}

But I need a full error, I'm getting full error in the visual studio terminal.

How can I add this error to the Log message?
