Hi Danny, Jumping in late on this thread, but wanted to remark that you might not need to go through al this if you switched from doing GET’s to this endpoint to using POST or PUT..

(note: you will have to explicitly commit the update transaction) Ex: xdmp:spawn-function(function() { xdmp:document-insert("/2014/11/20/danny.jpg", $temp_image, xdmp:default-permissions()), xdmp:commit() }, <options xmlns="xdmp:eval"> <transaction-mode>update</transaction-mode> </options>) Thanks. -jb From: Danny Sinang <[email protected]<mailto:[email protected]>> Reply-To: MarkLogic Developer Discussion <[email protected]<mailto:[email protected]>> Date: Wednesday, March 11, 2015 at 2:34 PM To: general <[email protected]<mailto:[email protected]>> Subject: Re: [MarkLogic Dev General] REST API call results in XDMP-UPDATEFUNCTIONFROMQUERY I think it's working now.

My question is, is there a workaround for this ? I already tried wrapping the document-insert call with xdmp:spawn-function, but that didn't work either. Below is the code.
