Wenn beispielsweise ein Code irgendwann in der Mitte, in einer anderen Abhängigkeit oder in einer *Pfadoperation*, ein „Rollback“ einer Datenbanktransaktion macht oder eine andere Exception verursacht, empfangen Sie die Exception in Ihrer Abhängigkeit.

Sie können also mit `except SomeException` diese bestimmte Exception innerhalb der Abhängigkeit handhaben.

Por ejemplo, si algún código en algún punto intermedio, en otra dependencia o en una *path operation*, realiza un "rollback" en una transacción de base de datos o crea cualquier otro error, recibirás la excepción en tu dependencia.

Por lo tanto, puedes buscar esa excepción específica dentro de la dependencia con `except SomeException`.

	if err = selfupdate.CommitBinary(opts); err != nil {
		if rerr := selfupdate.RollbackError(err); rerr != nil {
			return AdminError{
				Code:       AdminUpdateApplyFailure,
				Message:    fmt.Sprintf("Failed to rollback from bad update: %v", rerr),
				StatusCode: http.StatusInternalServerError,
			}
		}
		var pathErr *os.PathError
		if errors.As(err, &pathErr) {
			return AdminError{
				Code: AdminUpdateApplyFailure,

Por exemplo, se algum código em um certo momento no meio, em outra dependência ou em uma *operação de rota*, fizer um "rollback" de uma transação de banco de dados ou causar qualquer outra exceção, você irá capturar a exceção em sua dependência.

Então, você pode procurar por essa exceção específica dentro da dependência com `except AlgumaExcecao`.

For example, if some code at some point in the middle, in another dependency or in a *path operation*, made a database transaction "rollback" or created any other exception, you would receive the exception in your dependency.

So, you can look for that specific exception inside the dependency with `except SomeException`.
