PDI ServiceDesk app issue: This application ID already exists

mburgess — Tue, 09 Sep 2025 15:39:56 GMT

I have recently signed up for a ServiceNow developer account and requested an instance. However when I try to add the only app I have available (the ServiceDesk), no matter what I choose for an application ID it says the ID already exists. I found a post saying to clear your cache and reload, upgrade to the latest version, and if all else fails release the instance and request a new one. I have tried all of these twice and still get the same error. Has anyone else seen this? If so did you get it fixed?

Thank you in advance!

Hi MBurgess, Since you’ve already tried clearing cache, upgrading, and even requesting a new instance, maybe it’s something stuck on ServiceNow’s side.

Try using a completely unique app ID like adding your initials + numbers (servicedesk_mb123) and see if it works.
If not, probably the only real fix is to contact ServiceNow support they can check if your account or app ID got stuck somewhere.
Hope this helps!
Thanks & Regards,

The same here, I'm not able to create any app even with random characters due to error:

This application ID already exists. Try entering a different one.

Nobody really cares for 3 weeks?
