Hi everyone,
I'm following the guided path on Becoming a Traditional Web Developer and I've almost finished it. I'm working on 11.6x-Accelerated UI Development Exercise. Part 6a) tells me to publish my application to the server:

My module is valid and there are no errors shown:

But when I try to publish my application, I get a notification saying: "It was not possible to save the module."

Does anyone know why this might be the case, when the module is valid and I have no errors? How do I fix it?
Can you save to the disk? if yes save, close service studio and open again or try to update to the last version, open the file and try to publish.
