Hit "application was null" on now-sdk install — is there a PDI-friendly path?

[skfinch1984]

Hey,

Running into a wall on now-sdk install against a Australia PDI and would love a pointer.

What happens
[now-sdk] Attempting to log into instance https://.service-now.com
[now-sdk] ERROR: Exception occurred while installing application
Unable to install application as application was null

Login succeeds, build succeeds, install fails the moment the package hits the server.
Syslog stack trace:
com.sn_appclient_bootstrap.ScopedAppUploadProcessor.uploadAndInstallApp(line 251)
Already tried

• SDK 4.6.0 on Node 20.18+, fresh now-sdk init with the basic template, brand-new scope name.
• sn_glider (ServiceNow IDE) v4.1.1 active, latest in the Store.
• sn_appclient (Scoped App Client) v29.0.4 active.
• sn_appclient.app.install.offline set to true.
• API user has admin plus sn_appclient.app_client_user.

What seems to be missing
sn_try_build_agent looks like a PDI prerequisite based on one community thread, but it's blocked on entitlement-gated dependencies.

Question
Is there a way to get now-sdk install working on a standard PDI without installing the full Build Agent product? Or is a paid dev instance the only option?

Thanks in advance!

Do you have a plugin installing? I’ve seen that if the worker is in using pulling update sets or installing plugins--Billy Matthews719.439.5484On Apr 20, 2026, at 1:39 PM, skfinch1984 ***@***.***> wrote: Hey, Running into a wall on now-sdk install against a Zurich PDI and would love a pointer.

Thanks for the steer! Checked our instance though and it looks idle, no plugin installs, update-set loads, or background workers running when we retry. Every install attempt is just recorded as a failed Zip Installation with the same "application was null" message. The IDE plugin activation did happen earlier but finished before any of our failed attempts.

Have you run now-sdk build before you did install ?

The only requirement for SDK is that a recent version of the IDE is installed, and that you are of admin role.

I'll actually defer to #55 (comment) which is likely the correct issue of an unhelpful error message on scope problems

[skfinch1984]

Yep it was, you are right, those error messages dont tell anyone anything :)

Hi @skfinch1984, Can you confirm the app scope that you created and also verify if it matches the scoped prefix allowed based on the sys_properties glide.appcreator.company.code

[skfinch1984]

Thanks , that was spot on! Those error messages are not very helpful at all.

[venkat-kaluva]

Yes, I agree. We'll address this by ensuring that the relevant errors are surfaced.
