HTTPRequest.failure

HTTPRequest.failure() method

Access information about the request's failure.

Signature:

class HTTPRequest {
  failure(): {
    errorText: string;
  } | null;
}

Returns:

{ errorText: string; } | null

null unless the request failed. If the request fails this can return an object with errorText containing a human-readable error message, e.g. net::ERR_FAILED. It is not guaranteed that there will be failure text if the request fails.

Remarks

Example

Example of logging all failed requests:

page.on('requestfailed', request => {
  console.log(request.url() + ' ' + request.failure().errorText);
});
