/**
* @deprecated Import error classes directly.
*
* 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.
* }
* }
* ```
