And I can confirm that my code now also runs when MIXUPDATES=true
Although the code isn't meant to be shared yet as it's very much WIP here's the example I"m running: https://github.com/xokomola/origami-examples/blob/master/check/check-demo.xq
It's running all the Origami test cases via a custom built test harness (tests are evaluated via xquery:eval).

Hi Marc, hi Andy,
Confirmed, it seems to be the MIXUPDATES option. Once again, I noticed it’s tricky to statically detect which dynamic function calls will perform updates. Obviously, in the given case, there was no updating code at all, so the error message was a bit misleading.
Feedback on the MIXUPDATES option is always welcome. I have just uploaded a new snapshot [1].

Hi Christian,
Yes, I think so. I think MIXUPDATES=true could be the difference. I almost forgot about these as I always run basex from a Gradle script which sets these [1]

Hi Marc,
It runs fine on my environment. Could you give me some more information on your set up (have you assigned any non-default options)?

Hi Christian,
Seems to work fine with latest snapshot with some straightforward cases but I do get an error in some cases which I cannot understand. Though I appreciate that it may be difficult to support all types of dynamic calls.
The error is: [bxerr:BXXQ0001] No updating expression allowed.
I am not using updating expressions. I also tried this in my little test project and it runs against the same error. I haven't been able to pinpoint it yet as it happens deep in the bowels of the code. When I'm able to I will let you know.
You can use a simple/small set of unit tests to verify [1]. I've %unit:ignored the last test that causes the error above.
Cheers, --Marc

Hi Marc,
This was a deliberate restriction: As maps and arrays are function items, and as they can contain references to other functions that have been declared in the evaluated query, it is generally tricky to evaluate and return them dynamically.
However, I spent some more thoughts on the underlying semantics, and I may have found a solution that overcomes some of the earlier limitations.
A new snapshot is available [1], which now allows you to return function items (incl. maps and arrays) as result of xquery:eval. Your testing feedback will be welcome.

Hi,
I'm trying to return a map or an array from xquery:eval. Seems this is not possible, yet the signature says it returns item()*
xquery:eval('1 + 1') => 2 xquery:eval('[1,2]') => ERROR: [FOTY0014] Items of type array(*)have no string representation. xquery:eval('map { "x": 10 }') => ERROR: [FOTY0014] Items of type map(*) have no string representation.
BTW: I saw that xquery:eval#3 is documented as returning item() while the other arities return item()*
Tested on 8.3, haven't tested yet on 8.4beta but it's trivial to repro I figure.
