The [`CommonError`](https://error.angular-package.dev/draft-5/commonerror) abstract object to throw an [identified](https://error.angular-package.dev/draft-5/basic-concepts#identification) error with a [solution](https://error.angular-package.dev/draft-5/basic-concepts#fix) to the described [problem](https://error.angular-package.dev/draft-5/basic-concepts#problem), additional [type](https://error.angular-package.dev/draft-5/basic-concepts#type), and [range](https://error.angular-package.dev/draft-5/basic-concepts#range) built on the [template](https://error.angular-package.dev/draft-5/basic-concepts#template).

### `CommonErrors`

The [`CommonErrors`](https://error.angular-package.dev/draft-5/commonerrors) object represents the storage of errors with [unique identification](https://error.angular-package.dev/draft-5/basic-concepts#unique-identification) numbers.
