## E0178: 'await' cannot be followed by an arrow function; use 'async' instead

Arrow functions can contain `await` if they are marked `async`. It is an error to write `await` instead of `async` when making an arrow function:

    app.get("/", await (req, res) => {
      await doHomePage(req, res);
    });

To fix this error, write `async` instead of `await`:

    app.get("/", async (req, res) => {
      await doHomePage(req, res);
    });
