@servicenow/sdk — Release Notes

Version: 4.6.0
Availability: npm — https://www.npmjs.com/package/@servicenow/sdk

🚀 Overview

Version 4.6.0 adds several new Fluent APIs, Custom Action support, improvements to AIAF and NASK, and a range of bug fixes.

New Fluent APIs

Custom Actions & Flow Enhancements

This release significantly expands Flow and Subflow authoring capabilities:

• Author Custom Actions — Custom Action definitions can now be created directly in Fluent with typed step references for IntelliSense and compile-time safety. Script steps are externalized to separate files for a better editing experience.
• Call Subflows from Flows and Subflows — Flows and Subflows can now invoke other Subflows as steps.
• Call Custom Actions from Flows and Subflows — Custom Actions can be used as steps within Flows and Subflows.
• Reference global and cross-scope Subflows and Actions — Flows and Subflows can reference Subflows and Custom Actions from global scope or other application scopes via the SDK's dependency mechanism.

Inbound Email Actions

The new InboundEmailAction API enables declarative creation of inbound email action records (sysevent_in_email_action).

Service Portal

Additional Service Portal APIs have been added to round out existing coverage:

• SPHeaderFooter for creating header and footer records
• SPPageRouteMap for defining page-to-page redirect mappings within a portal

Form

The Form API is now available, enabling declarative configuration of forms directly in Fluent.

Updates to Existing APIs

AI Agent Framework (AIAF)

Automatic ACL Generation for AI Agents

AiAgent and AiAgenticWorkflow APIs now automatically generate the required security ACL records as part of the build. Developers no longer need to define ACLs separately for their agents.

Now Assist Skill Kit (NASK)

Auto-generated Standard Outputs

When the outputs array is omitted from a NowAssistSkillConfig, the five standard skill outputs (response, provider, errorcode, status, error) are now automatically generated. Only define outputs when adding custom outputs beyond these defaults.

Expanded Input Data Types

Skill input attributes now support additional data types: glide_record, simple_array, json_object, and json_array — in addition to the existing string, numeric, and boolean types. A tableName is required when using glide_record, and an optional truncate flag is available for scalar types.

New Features & Changes

Stricter sys_id Conflict Detection

The build now distinguishes between two types of sys_id conflicts:

• Fluent vs Fluent conflicts (two .now.ts files defining the same record) always produce an error.
• XML vs Fluent conflicts continue to respect the --errorOnConflict flag.

explain Command Improvements

The now-sdk explain command has been significantly improved:

• More accurate results using tag-based lookup.
• --list displays the full index of available topics.
• --format=raw outputs raw Markdown.
• --peek shows a brief summary without opening the full document.

# Browse all available topics
now-sdk explain records --list

# Preview a topic without opening the full doc
now-sdk explain records --peek

Other Changes

• The Table API now supports creating dictionary override records (sys_dictionary_override) directly, without needing a separate API.
• ScheduledScript script fields now support modules.
• Project templates have been simplified: tsconfig relocated to src/, unnecessary index file removed, and a jsconfig added for JavaScript templates.

Bug Fixes

Now Assist Skill Kit (NASK)

• Fixed duplicate tool inputs and outputs being generated in certain configurations.
• Fixed issues with UI action handling in skill definitions.
• Fixed delete functionality for skill records.
• Fixed active flag not being correctly applied during build.

Service Portal

• Fixed duplicate M2M records being created for catalog and knowledge base items when using the Service Portal Fluent API.
• Fixed missing portal settings and availability config fields on CatalogItemRecordProducer that were already supported on CatalogItem (hideAddToCart, hideAddToWishList, hideDeliveryTime, hideQuantitySelector, hideSP, image, model, mobilePictureType).

Front-end Framework Support

• Fixed source manifest generation failing when a project contains multiple UI pages with different entry file names.
• Fixed source artifacts missing assets that were imported via CSS url() references.

Flows & Custom Actions

• Fixed a regression where flow variable column types were lost during build.
• Fixed a data type mismatch in datapill expressions where reference types were incorrectly treated as strings.
• Fixed empty strings being silently accepted for mandatory inputs in core actions.

Transform

• Fixed HTML entities being appended as individual characters instead of being decoded during transform.
• Fixed a TypeScript error after transform where "GUID" was not recognized as a valid flow data type.

Build

• Fixed UI Page build failures when inline scripts contain unescaped < operators or HTML literals.
• Fixed object keys that start with a digit not being quoted, which caused JavaScript parse errors.

Configuration

• tableDefaultLanguage in now.config has been renamed to defaultLanguage. The old name continues to work but is deprecated.
