Hi @arose_5538 ,
Looks like this was indeed a regression in 2024.23 as a result of upgrading the JSON library we were using... I guess it's a lot more strict.
Of course, upack is also wrong, but for whatever reason it worked before. anyway it's an easy fix, and will be fixed in the next maintenance release (scheduled Feb 7) of ProGet via PG-2884.
In the meantime, you can just downgrade to 2024.22.
And I checked pgutil 2.1.0 will be released soon :)
Cheers,
Alana
