You need a valid App Engine Studio license to continue working.

Today I got an error while trying to open App Engine Studio:

I tried changing user role, added snc_internal, released and provisioned PDI, configured what I could and still nothing....

Could anyone help me with it?

Hi Kamil

The only workaround I have found is downgrading to Xanadu.

Like you I am facing the same Issue. Its very frustrating. I have tried all of the following several times and can confirm they do not resolve the issue:

1) Changing Roles from AES to Admin then logging out and in - Does not work

2) Changing Roles from Admin to AES then logging out and logging in - Does not work

3) releasing the instance and requesting a new one (tried multiple times) - Does not work

4) Downgrading to Yokohama - Does Not word

If you do find a resolution, please do let me know

Best

Raj

Hi @KamilKowalczyk

No need to worry — this is a known issue with PDIs at the moment. Please try the following steps:

Recommended Steps

Log in to developer.servicenow.com
Go to your Profile
Select Change User Role
Change the role from AES to admin
Save the changes
Log out and log back into your PDI

If the issue still persists, release the instance and provision a new one.

This behavior has been reported quite frequently recently. Since PDIs don’t have official support, it might take a few tries — but please keep trying.

Workaround (if it still doesn’t work)

Assign the admin role
Log out and log back in
Assign the AES role
Then, reassign the admin role again

This sequence has worked in some cases.

If it still doesn’t work, release the instance and request a new PDI with a lower version, and then upgrade it to the latest version afterwards.
