Maybe using json:serialize() rather than serialize?
In general if output:method is set to Json it should be sufficient to
return map{} or array{} or alternatively the XML version of a json
document without having to explicitly serialize ...

Thank you, Marco. So, the download issue seems to be with XForms
(XSLTForms) rather than BaseX. If I do a file upload from a plain HTML
form, the file download is triggered correctly. However, even though I
have set "application/json" as the Content-Type, the contents of the
downloaded file are an escaped string rather than a serialized JSON
object: e.g.,
"{\n \"key\": \"value\"\n}"
Is there a way to produce a properly serialized JSON file for download?

Hi Tim,
downloading from a browser when posting a form is usually a bit
tricky. For me it always ended up with the creation of an
artificial <a ...> element with an href crafted from the form
parameters and with an attribute download="filename.ext" added to it.
Anyway you could try with returning a "forced"
application/octet-stream Content-Type header ....

Hello,
I am posting a JSON doc to a RESTXQ function from XForms and
trying to set a Content-Disposition header to trigger a file
download. Is this possible to do without first saving the JSON
doc as a file? Right now, the RESTXQ function returns the correct
headers, but does not force a file download dialog.
Thanks in advance!
