Hello,
I am trying to implement an XForm for posting data via:
<xf:submission resource="http://localhost:8984/test" method="post"
serialization="application/xml" replace="all" />It should invoke the following query (in webapp):
module namespace page = 'http://basex.org/examples/web-page';
declare
%rest:path("/test")
%rest:POST("{$data}")
function page:hello ( $data as element() )
as element() { $data };But I get this instead: [image: image.png] TIA for any help, Robert.

Hi Robert,
Yeah, that’s not necessarily obvious, but the type of the document you post is „document-node()“ not element() — so simply change the function & argument types to document-node() and you will be fine.
Usually the the in-browser debugging > Network view helps with identifying such „low-level“ errors, yet I tend to use the command-line more often since I discovered httpie[1]
