errors

errors variable

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.

Signature:

errors: PuppeteerErrors;

Example

An example of handling a timeout error:

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