I think there is a typo in your POC somewhere, as it does not generate a fault. However, based on this hint, I was able to find and fix a harmless problem in the code generator. So I suspect your POC is working now.

Oh maybe there was something wrong due to the copy&paste.
Here is the original poc (https://transfer.sh/NlJBxn/poc3.sql), just for reference.
Thanks for the fix!
