I did it with the following query (originally from Mateusz's wikipedia/wikidata tool) but only the nodes are listed:

@matkoniecz You could try using "out:json" instead of "out:xml".

and it failed in the same way.
Tried your query, failed in the same way.
@matkoniecz your original overpass query does not return any data in overpass turbo, perhaps that is the issue?
If I create a challenge just using the node identifiers from your original query:
node(id:101409102,1018918855,117178037);out meta;
that works fine. Perhaps I don't understand what you're trying to do. Happy to help more!

Unlikely, note that https://www.openstreetmap.org/node/101409102 https://www.openstreetmap.org/node/1018918855 https://www.openstreetmap.org/node/117178037 had their links fixed - that is why they are not listed anymore.
I will try with a new data.

works in Overpass, but no tasks are created: https://maproulette.org/admin/project/50406/challenge/37105
@mvexel If you have time, try a mixed list with Nodes, Ways and Relations. I think this is the problem. If only one category of objects is used (like in your example only nodes), then it works. But if the object types are mixed, it doesn't work anymore.
@mcliquid Mixed geometries are supported, I created https://maproulette.org/browse/challenges/37126 with https://overpass-turbo.eu/s/1phk as a test.
@matkoniecz your most recent overpass query does not return any geometries. MapRoulette needs geometries to make tasks :) Instead of out meta try out center or out geom (you can leave meta but you usually don't need it)
I tried out center and out geom but MapRoulette created over 60,000 Quests. Overpass
I've already fixed the E8 hiking route because it's the longest way / most nodes but also this way will create 14 quests instead of one.
I'm pretty sure that the big relation crashed it. I've removed the E8 relation from the query and was able to create the challenge now: https://maproulette.org/browse/challenges/37131 Before I've got something over 60k quests now without relation 912994 there are only 576 quests left. Maybe the E8 relation is too big?
@matkoniecz your most recent overpass query does not return any geometries. MapRoulette needs geometries to make tasks :) Instead of out meta try out center or out geom (you can leave meta but you usually don't need it)
ops, I followed https://learn.maproulette.org/documentation/using-overpass-to-create-challenges/ that had out meta; (maybe it works only for nodes and not for ways? maybe use out center; in that example to be more idiotproof?)

https://overpass-turbo.eu/s/1phE works
tried also out geom
I created https://maproulette.org/browse/challenges/37135 with that query but leaving out the top statements:

relation(1182652);

So MapRoulette gets confused by those. We need to make that clearer. I opened a project to collect all the open tickets (and future ones) that have to do with improving the Overpass experience for challenge makers: https://github.com/orgs/maproulette/projects/1
https://github.com/orgs/maproulette/projects/1 is either private or a broken link
Also, maybe I done something wrongly or done test incorrectly - but this headers appeared to be fine in testing done for https://github.com/maproulette/maproulette3/issues/1908#issue-1505091071
Not sure what is going on.
@mcliquid https://maproulette.org/admin/project/50406/challenge/37205 seems to finally work
I opened a project to collect all the open tickets (and future ones) that have to do with improving the Overpass experience for challenge makers: https://github.com/orgs/maproulette/projects/1
That's a good project idea... I took a quick look and the code's parsing of overpass queries does not handle various orderings of the "Settings" statement. And the code adds additional settings when it thinks those are missing, so if the query is misinterpreted the other settings may be injected and essentially corrupts the query.
A few overpass Settings examples and how it influences the settings used in the query sent to overpass:
[out:json];works fine, and[timeout:X];works fine (although it is changed to[out:json][timeout:X];)[out:json][timeout:X]works fine[out:json];(space at the front) breaks, resulting in[out:json][timeout:Y]; [out:json];[out:json][timeout:X];(whitespace) is broken, resulting in[out:json][timeout:Y]; [out:json][timeout:X];- Conflicting timeout: X is from the user and timeout Y is from the maproulette settings
[timeout:X][out:json];is technically broken with the result being[out:json][timeout:X][out:json];[out:xml];breaks, resulting in[out:json][timeout:Y];[out:xml];
