Here are the details of the issue:
- In PDIs running Yokohama Patch 4, Patch 5 and Patch 6, as well as in Zurich release, it is not possible to open App Engine Studio.
- The following error message is displayed: “You need a valid App Engine Studio license to continue working.”
- This issue does not occur in PDIs running Xanadu, Washington DC, or in Yokohama up to Patch 3. I have a Yokohama PDI in Patch 3 and AES is working fine! So, the issue started in Patch 4.
- I have requested and tested several PDIs across these versions, and the behavior is consistent.
I have also checked and there are multiple threads reporting the same problem here in ServiceNow Community. Some responses suggest going to the Developer Site, selecting “Change User Role”, switching the role to App Engine Studio Creator, and then back to Admin. Unfortunately, this workaround has never solved the problem in any of my tests.
I believe that ServiceNow needs to do something about this issue. This is not an isolated case! We don't have nothing to do!
Solved! Go to Solution.

Hi everyone!
Just to let you know... I requested a PDI in Zurich (patch 1) and App Engine Studio was working! After that, I also requested a PDI in Yokohama (patch 5) and AES was working too.
So, I think ServiceNow fixed this issue. 😊

Hi @Dr Atul G- LNG!
Thank you!
I've tried it but after the upgrade, AES starts to show the license issue. 😥

Oops… then I think there’s no other way, mate.
Generally, changing the role should work — give it a try, it might do the trick.
If my response proves useful, please indicate its helpfulness by selecting " Accept as Solution" and " Helpful." This action benefits both the community and me.

Hi @Nikhil Bajaj9!
Thank you!
Although I didn't find anything helpful in KB0010311. They talk about a feedback button on Developer Site but I didn't find it.
