Hi Uwe, the line points at this code: https://github.com/geotools/geotools/blob/21.1/modules/unsupported/wfs-ng/src/main/java/org/geotools/data/wfs/internal/v2_0/StrictWFS_2_0_Strategy.java#L643
Agree with Mark, it seems related to the output format, the code is looking for an "allowed values" entry that is not found (and it seems like it ought to to be there, or at least, the code assumes to always find it). Not sure what's the case here. Mind, the WFS store is, as you can see by the link, unsupported, so it's probably quicker to work around its limitations rather than get a fix... but if you want to contribute a fix, we're surely happy to get a pull request <https://github.com/geotools/geotools/blob/master/CONTRIBUTING.md>.
