App Engine Studio: cannot submit application for approval

[_calvinr]

Hello and thanks for reading.

Using the App Engine Studio feature, I am unable to submit my application for approval after completing all of the tasks. This issue is persistent across users, including the super-user "System Administrator" account.

After completing the build of tables for data, experiences for catalog items and portal, building automation pipelines, adding security permissions, the submission button remains greyed out with the message:

"there was an error while retrieving your application deployment information. Contact your admin in order to submit your app."

Doesn't matter if I base my application on a template or if I build everything from scratch. This is the forth app I've tried to build today, so eager to hear any ideas.

The main reason for it not working on a PDI is that you only have one instance in a PDI stack and don't have access to push things to the app repo. In a customer instance stack you'll have 3+ instances so there's somewhere for the app to go.

Does this mean I cannot test out the solution in a customer instance where I am using dev and test. The test instance will act as the production instance.

Customer instances should be connected to the repo so you'd be able to move the apps. PDIs (devXXXXX.service-now.com) are not connected to the app repo.
