I am just trying to run the Ext JS 3.3 examples as found here:

The example browser in the upper left loads without any tree attached (i.e., left panel is blank).
Looking at the console, it has thrown this error:

POST http://dev.sencha.com/deploy/ext-3.3...tree-data.json 413 (Request Entity Too Large)
If you just browse to the URL, there is not much data there. The error message seems to be complaining about the request, not the amount of data the server wants to send.
I don't see anything especially alarming in the headers. There is some semi-myterious cookie values from Google Analytics. The Sencha site appears to be employing that, so I don't think that should be an issue.

  • POST http://dev.sencha.com/deploy/ext-3.3...tree-data.json HTTP/1.1 Host: dev.sencha.com Proxy-Connection: keep-alive Content-Length: 13 Cache-Control: max-age=0 X-Requested-With: XMLHttpRequest Origin: http://dev.sencha.com User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.22 Safari/537.36 Content-Type: application/x-www-form-urlencoded; charset=UTF-8 Accept: */* Referer: http://dev.sencha.com/deploy/ext-3.3...t-browser.html Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Cookie: __utma=237862421.274044260.1376605232.1376605232.1376669224.2; __utmb=237862421.2.10.1376669224; __utmc=237862421; __utmz=237862421.1376605232.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none)

And the Form Data is simply:
  • node:

Anybody else able to verify the same behavior?
Any ideas about how to resolve this problem?
