Hi @Francisco Carreira 

I have version 11.10.16 (build 40208) installed and works as expected.

I was avoiding the update for now but will probably end up doing it if no solution is found.

Thank you.

Hi Francisco,

This is kind of weird issue you are facing, so it would be better to report it to OutSystems team. Please raise a support case with OS team.

Thanks & Kind Regards,


Done that, waiting on an answer. I'm just trying to see if someone else has the same issue and if they figured out a solution.

Thank you,


I also had the same problem. Found no way to fix it so I upgraded Service Studio. Works fine with v11.10.16.
