I keep running into HTTP Error 413: Request Entity Too Large errors when using the clone_items function. It happens intermittenly with web maps and forms.

here is a sample traceback

Got this working...it was an IIS Setting blocking the request. Follow these instructions to fix. I set the “uploadReadAheadSize” to 20 mb
