fix(servicenow): read catalog item variables from the variables endpoint - #22159
Merged

GET /sn_sc/servicecatalog/items/{sys_id} returns 500 for record producers
on some instances ("TypeError: Cannot convert null to an object" in a
script include), so Get Catalog Item Variables failed for them.
/items/{sys_id}/variables returns the same variable objects for both
catalog items and record producers; the action already accepts either
response shape. Bumps the package and every component importing the app.

Other actions import the app file but do not call getCatalogItemVariables, so their behavior is unchanged and they keep their current versions.
getCatalogItemVariables changed in servicenow.app.mjs, and every ServiceNow action imports that file, so each gets a patch bump to republish against the new app code. Reviewer request on PipedreamHQ#22137. Co-authored-by: Cursor <cursoragent@cursor.com>

Restores item details (GET /items/{sys_id}) as its own action now that
Get Catalog Item Variables uses /items/{sys_id}/variables. Variables now
carry an options block saying where valid values come from, flag script
qualifiers that cannot be evaluated over REST, resolve javascript: reference
defaults as the signed-in user, and drop list collector filter-builder columns.

logic to recognize dot notation and single- or double-quoted bracket notation,

Search Catalog Items already returns the item details (price, recurring price,
type, mandatory attachment, catalogs, category). The only extra fields from
/items/{sys_id} are variables, which Get Catalog Item Variables covers, and
ui_policy/client_script, which ServiceNow returns empty for non-admin users.

@srinivas56711 I ran some evals via the Eval Monster, but I'm getting a failure for one of them. Claude's suggestion is to trim the per-variable passthrough in describeVariable to a curated field set.
|
Passing every ServiceNow variable field through made large record producers overflow the agent's tool-output budget. Keep id, name, label, type, mandatory, value and choices plus the added options and default flags, and read the script-default table from options.table.

describeCatalogVariables (PipedreamHQ#22159) keeps only the fields an agent needs to fill the form, which also dropped each variable's help_text: the guidance ServiceNow shows under the field (e.g. 'If not listed, please select "Other"'). Keep it when set; empty values are still dropped so the trimmed response stays small (+206 bytes on a 9-field record producer). Bumps the actions that import common/utils.mjs and the package version.

Summary
Get Catalog Item Variables fails for some record producers. This PR points it at ServiceNow's variables endpoint, which works for both catalog items and record producers. It also makes the variables output say where each field's valid values come from, so an agent can fill mandatory fields and submit as the signed-in user.
This supersedes #22137 (opened by @akshaykumarg, whose commits are kept here). It adds the version bumps @diegoaad asked for in review.
Problem
getCatalogItemVariablescalled the item-details endpoint,GET /api/sn_sc/servicecatalog/items/{sys_id}, and returned its.variables. For some record producers ServiceNow returns HTTP 500 while building that payload:{"error": {"message": "Cannot convert null to an object.", "detail": "TypeError: Cannot convert null to an object. (sys_script_include.<id>.script; line 30)"}, "status": "failure"}The variables also come back with raw scripts where an agent needs values. Reference defaults look like
javascript:gs.getUserID();, and reference qualifiers look likejavascript:getMyRoleDelegationGroups().Changes
Get Catalog Item Variables (
0.0.5→0.0.6)GET /api/sn_sc/servicecatalog/items/{sys_id}/variables. This is an out-of-the-box Service Catalog API operation ("Variables of an item"). It's widely used but isn't listed in ServiceNow's published API reference.optionsobject to every choice-based variable, including variables inside containers:source: "choices": the valid values are in the inlinechoices. For lookup select boxes, ServiceNow has already evaluated the qualifier as the calling user, including script qualifiers.source: "table"(reference, Requested For, list collector): look upoptions.tablewith Get Table Records, usingoptions.querywhen the qualifier is a plain encoded query.qualifier_unresolved: truewithqualifier_script: the qualifier is a script. Scripts can't be evaluated over REST, and the Table API silently ignores a whole-script query and returns every row, so the action flags it instead of passing it on.depends_onlists thecurrent.variables.*it reads.qualifier_unavailable: true: list collectors, which the API returns without their qualifier.javascript:defaults on reference variables by querying the referenced table as the user (sys_id=<script>). The result is used only if it's exactly one record. The original script stays indefault_script. Other script defaults take ServiceNow's evaluateddisplayvalue. Defaults that can't be resolved are left blank withdefault_unresolved: true.columns. That's filter-builder UI metadata (about 42 KB persys_userlist collector), not the list of options.choices. Mandatory fields need the full server-evaluated list for Add Item to Cart, Order Catalog Item and Submit Record Producer to succeed. ServiceNow already caps lookup choices atglide.ui.lookup.max_rows.Get Question Choices (description only)
question_choiceusually needs a catalog admin role, so a signed-in employee gets a 403. It recommends the inlinechoicesfrom Get Catalog Item Variables instead.Get Current User (fix)
GET /api/now/ui/user/current_userreturnsuser_sys_id, but the action readsys_id, so it always threw "Unable to determine current user from session". It now readsuser_sys_id(falling back tosys_id). Verified as the employee below. Agents call this action while resolving Requested For, so the bug was failing the catalog evals.Verification
All calls ran against a ServiceNow developer instance.
