Due to a few issues with the Slack integration, such as encountering a limit of 100 entries on reference fields, the following is a compromise solution

Slack will use a workflow to create a message and URL to user and redirect them to ServiceNow portal 'Report an Issue' record producer.

Steps to create a Slack workflow

1. Login to Slack workspace (please contact Slack admin for workspace access)
2. Click on your workspace name in the top left, Select Tools from the menu and Click on Workflow Builder, which will open in a new window.
3. From Workflow Builder, click Create in the top right.
4. Enter a name for your workflow, then click Next.
5. Click Select next to the trigger(Shortcut) that you'd like to use.
6. Select a channel from the drop-down menu.
7. Add a short name for your workflow that will be visible in the attachments and shortcuts menu.
8. Click Next.
9. Click Add step to open the step library.
10. Select 'Send a message' step.
11. Click Add next to the step that you’d like to use.
12. Select 'Channel where workflow started' for 'Send this message to:'
13. Update message text with ServiceNow instance URL for 'Report an Issue' record producer, click on hyperlink button and add text and link
14. Click on 'Publish'

Haven't tested these all recently within global/local scopes, so feel free to have a play! option 1 use an encoded query embedded in the GlideRecord , e.g. var grProf = new GlideRecord ( 'x_cls_clear_skye_i_profile' ); grProf . addQuery ( 'status=1^ owner=NULL ' ); grProf . query (); even better use the glideRecord addNotNullQuery or addNullQuery option 2 JSUtil.nil / notNil (this might be the most powerful. See this link ) example: if ( current . operation () == 'insert' && JSUtil . notNil ( current . parent ) && ! current . work_effort . nil ()) option 3 there might be times when you need to get inside the GlideRecord and perform the check there, for example if the code goes down 2 optional routes depending on null / not null can use gs.nil : var grAppr = new GlideRecord ( 'sysapproval_approver' ); var grUser = new GlideRecord ( 'sys_user' ); if ( grUser . get ( 'sys_id' , current . approver )){

Classic UI : var sURL_editparam = gs . action . getGlideURI (). getMap (). get ( ' sysparm_aparameter ' ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); } Portal : var sURL_editparam = $sp . getParameter ( " sysparm_aparameter " ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); }

Call a script include to apply a reference qualifier on a catalog item variable: - variable reference qualifier dependent on another variable selection, in this case a variable referencing sys_user (requested_for) On the catalog item form. variable name to apply ref qual filter : retail_equipment variable reference qualifier (on cmdb table ): javascript : new refqual_functions (). lostStolen_getAssignedCIs (); client-callable script include ( refqual_functions) function : lostStolen_getAssignedCIs : function (){ //--called from variable set client script, for lost/stolen request (service catalog) gs . log ( current . variables . requested_for , 'retail_lostStolen_getAssignedCIs' ); return ( 'install_statusNOT IN8,7owned_by=' + current . variables . requested_for ); //owned_by=1269b79937f1060041c5616043990e41install_statusNOT IN8,7 },
