errors variable

Warning: This API is now obsolete.

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.


errors: PuppeteerErrors;


An example of handling a timeout error:

try {
await page.waitForSelector('.foo');
} catch (e) {
if (e instanceof TimeoutError) {
// Do something if this is a timeout.
