# View Source WithClauseError exception (Elixir v1.16.3)

An exception raised when a term in a `with/1` expression does not match any of the defined `->` clauses in its `else`.

The following fields of this exception are public and can be accessed freely:

- `:term` (`term/0`) - the term that did not match any of the clauses

For example, this exception gets raised for a `with/1` like the following, because the `{:ok, 2}` term does not match the `:error` or `{:error, _}` clauses in the `else`:

    with {:ok, 1} <- {:ok, 2} do
      :woah
    else
      :error -> :error
      {:error, _} -> :error
    end
