Hi Vincent,
Could you give us additional information on how you dispatch your HTTP
request? With the following request, everything seems to work fine:
input.json:
{ "items": [ ["item 1", "item 2", "item 3"] ] }
command:
curl -H"Content-Type:application/json" -XPOST -Tinput.json "
http://localhost/my/function";
In addition, feel free to run your query with the latest snapshot [1],
which includes fixes for the processing of data that is incoming through
RESTXQ endpoints.
Best,
Christian
