Error returned instead of returning empty sequence about rumble HOT 3 CLOSED

Thanks, Ingo.

This is not a syntax error. [0] filters for a sequence position (in this case, the sequence only one has one array), but positions start at 1, so $o.choices[0] should return an empty sequence. Then, eq returns () as well and where should be false, so the overall query should return ().

But there is indeed a bug in our iterators that we need to fix.

FYI if you need the first choice, then the syntax for this should be

$o.choices[[1]]

(array lookup is [[ ]], and positions start at 1 in JSONiq).

OK, I think I understand the difference now. So, as you say, it's only the problem with the iterator.

I am happy to announce that this is now solved :)
