Cannot add a new Application in App Engine Studio

[Moritz Becker1]

Hi All,

I am currently starting out on my official learning path for the ServiceNow Application Developer, but am currently stuck at creating a new Application in my lab instance.

I have tried multiple times with different names and values but I always get the same error stating that "Your app encountered an unexpected error while being created. Details: Failed to create templated object, details: This scope is already taken by another application".

Although I followed everything in the tutorial I cannot get it to work.
I am on Washington DC release.

I pulled the log line that corresponded to the error message, it looks like this:

I also cannot debug the flow that creates the application (Application Template - Scoped app template with roles), because it is a protected app file.

I'd be very glad if anybody has any idea of what could be wrong.

Farewell

I had a similar issue in the lab of NowLearning's "Introduction to App Engine Studio for Citizen Developers" course.
I will share the solution.
You can create an application by naming it e.g. “safe_YYMMDD”(YYMMDD:date). In App Engine Studio, name = application scope, so you need to specify a unique name.

Amazing!  Thank you for the suggestion.  I'm very new to SN and this really tripped me up.  I don't understand why ServiceNow hasn't fixed this in over 6 months.  It's very discouraging as a new user already not knowing what to do and then encounter an error not described in the training module.
