 * Puppeteer methods might throw errors if they are unable to fulfill a request.
 * For example, `page.waitForSelector(selector[, options])` might fail if the
 * selector doesn't match any nodes during the given timeframe.
 *
 * For certain types of errors Puppeteer uses specific error classes. These
 * classes are available via `puppeteer.errors`.
 *
 * @example
 * An example of handling a timeout error:
 *
 * ```ts
 * try {
 *   await page.waitForSelector('.foo');
 * } catch (e) {
 *   if (e instanceof TimeoutError) {
 *     // Do something if this is a timeout.
 *   }
 * }
 * ```
