AES - Unable to create application – "Failed to create templated object, details: Missing parameter"

[louis-engel]

Hi everyone,

I'm experiencing a persistent issue when trying to create a new application in both App Engine Studio and Studio in my PDI.

When trying to create a new app in App Engine Studio:

• I entered "test" as the application name.

• After clicking Create, I get the following error:

Unable to create this application.
Go back to the create app experience and enter a different scope name.
Details: Failed to create templated object, details: Missing parameter

When trying to create an app from a template:

• I receive this error:

Template Execution Failure
Cannot decode: java.io.StringReader@4cff862a

When trying to create an app in Studio:

• I get the same "Failed to create templated object" error unless I choose the Global scope, in which case the creation works

What I’ve tried so far:

• Used different app names and scope names (simple, lowercase, no spaces or special characters)

• Cleared browser cache, tried incognito mode, different browsers

• Fully reset the instance

• Requested a brand new instance (on Yokohama)

• Tried using a completely new developer account

Despite all this, I cannot create any application in AES at all – neither from scratch nor from a template.

Thanks in advance,
Louis

Hi @louis-engel 

It is a known issue in PDi and many other users reported the same.

@louis-engel 

If this is for your PDI then I agree with what Atul has shared.

Recently many members have reported this so we can't help much as PDIs are not supported by ServiceNow team.

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi @Ankur Bawiskar , hi @Dr Atul G- LNG ,

Thank you both for your responses – I appreciate it.

However, I still have a few important questions:

1. If PDIs are hosted and maintained by ServiceNow, who is responsible when a platform-level feature like app creation suddenly breaks?
   This issue clearly started just a few days ago – I had no problems creating apps before.

2. Is this being tracked internally as a known bug, and is there any ETA for a fix?

3. Where can this issue be officially reported, if not here in the forum?
   Because right now, it’s affecting many developers and completely blocks working with scoped applications.

I understand that PDIs come with no official support, but this seems like a backend/template issue that only ServiceNow can resolve.
Even brand new instances are broken out of the box, which suggests the platform itself has a problem – not just one user's setup.

Thanks again for your time.

Best regards,
Louis

Hi @louis-engel 

However, I still have a few important questions:

1. If PDIs are hosted and maintained by ServiceNow, who is responsible when a platform-level feature like app creation suddenly breaks?  ---> Atul Technically, it’s ServiceNow, but since PDI doesn’t come with support, it’s tough to pinpoint a single name.
   This issue clearly started just a few days ago – I had no problems creating apps before.

2. Is this being tracked internally as a known bug, and is there any ETA for a fix? 

Atul: From community no one can tell ETA for same, we all can wait only mate.

1. Where can this issue be officially reported, if not here in the forum?

Atul:  As there is no PDI support so no dedicated forum for this, just wait buddy
