Hi Alejandro, Sorry for the delay. I looked at that script and it didn’t seem like it would allow for me to force the right python. What I need is something like where the scripts get generated, I just need to change the top line of the scripts below, but since they’re regenerated when services are stopped, I need to do it programmatically. Maybe this could be made as a property, which is optionally configurable?
