Unable to Create NLU Intent in PDI (Zurich) – "Connection to NLU Service is not available"

[11chetans]

Hi Everyone,

I am currently learning ServiceNow Virtual Agent and Natural Language Understanding (NLU) in my Personal Developer Instance (PDI).

I successfully created an NLU Model named "IT Issues", but when I try to create my first Intent (e.g., Outlook Issue), I receive the following error:

"Some features may not be available because the connection to NLU Service is not available. Please try again after sometime, if the issue persists log an issue with Support."

Environment

• Instance Type: Personal Developer Instance (PDI)
• Release: Zurich Patch 10
• Module: Natural Language Understanding (NLU)

What I have verified

• Successfully created the NLU Model.
• All required NLU plugins are installed and up to date:
  • NLU Workbench (com.snc.nlu_studio)
  • Proxy agent for connecting to NLU providers (com.glide.nlu.proxy)
  • Proxy Agent to the ServiceNow NLU server (com.glide.nlu.intent.discovery)
• Verified the system property:
  • glide.shared_service_scheduler.url = https://sncmlscheduler.service-now.com/
• Refreshed the instance, logged out/in, and retried multiple times.

My Question

• Has anyone experienced this issue in a Zurich Personal Developer Instance?
• Is this a known limitation or issue with PDIs?
• Is there any alternative solution or additional configuration required to create Intents in a PDI?

I've attached screenshots of the error and my NLU model for reference.

Any guidance or suggestions would be greatly appreciated.

Thank you!

Hi @11chetans 

I think this is expected behaviour in the PDI, but please have a look and confirm.

Common Causes & Fixes

• Personal Developer Instance (PDI): NLU and heavy AI microservices are often turned off or unsupported on free developer instances. If a training lab requires this, you may need to request manual validation from your course admin. [1, 2]

• Incorrect System Property: Check that glide.shared_service_scheduler.url is correctly set to https://sncmlscheduler.service-now.com/. [1]

• Unsynced Vocabulary: Go to the NLU Workbench, open Vocabulary Sources, and manually sync your source tables. [1]

• Machine Learning Settings: Navigate to your global application scope, reset machine learning configurations, and repair system properties. [1]

ServiceNow disables external NLU prediction and training servers on free Personal Developer Instances (PDIs).

Because ServiceNow hosts these Natural Language Understanding (NLU) capabilities on separate, shared cloud microservices, PDIs lack the background infrastructure access that paid enterprise instances enjoy.
