core-ajax with handleAs 'document' error 4xx

Is there a way to access to the content of the response of a 'core-ajax handleAs="document" request that receives a '4xx' http status code?

Add an error handler to your core-ajax element:

<core-ajax on-core-error="{{onError}}" ...>

Your callback function receives an event object, lets name it e. e.detail.response only contains an informative message string, but e.detail.xhr contains the original XHR response object.

Edit: Additional note when using handleAs="document": In this case an exception is thrown when using Polymer 0.3.4.

Uncaught InvalidStateError: Failed to read the 'responseText' property from 'XMLHttpRequest': The value is only accessible if the object's 'responseType' is '' or 'text' (was 'document').

This is the offending code

var response = xhr.status + ': ' + xhr.responseText;

So the error handling code doesn't check if the response type was set to document.

In this case you may need to use the core-xhr element directly.
