Hi @cedrus
Which version are you using? And which database are you connecting to?
I'm not quite sure what's going on, but can you check what actual query is by opening developer tools in the browser, go to Network tab, run the query again to make the POST request show, select the request, go to Response sub-tab, find data>native_form>query
(This is how it looks in Firefox - I think Chrome is similar, but might be slightly different)
