# Overview

## `Error {}`

The `Error` object is an extension of the [`CommonError`](https://error.angular-package.dev/commonerror) class and is thrown when a runtime error occurs with a [message](https://app.gitbook.com/s/23iV8ygEQUrhqw7I3D8g/~/changes/lXvTfsmAkHoNRKsQjxlq/commonerror/accessors/get-message) built from a [solution](https://app.gitbook.com/s/23iV8ygEQUrhqw7I3D8g/~/changes/lXvTfsmAkHoNRKsQjxlq/commonerror/accessors/get-fix) to the described [problem](https://app.gitbook.com/s/23iV8ygEQUrhqw7I3D8g/~/changes/lXvTfsmAkHoNRKsQjxlq/commonerror/accessors/get-problem) but with additional identification, on the [template](https://app.gitbook.com/s/23iV8ygEQUrhqw7I3D8g/~/changes/lXvTfsmAkHoNRKsQjxlq/commonerror/accessors/get-template).
