Event Field Mapping does not work when Threshold is enabled in Even Rule post upgrading to Newyork. - Known Error

Event Field Mapping does not work when Threshold is enabled in Even Rule post upgrading to Newyork. Description Event Mapping field rules does not work consistently

Steps to Reproduce

Create an event field mapping rule. Create an event rule with Threshold disabled. Create em_event and confirm in em_alert the field mapping rule is working. Enable Threshold in the event rule created previously. Create em_event and confirm in em_alert that the field mapping rule is not working. Workaround This problem has been fixed. If you are able to upgrade, review the Fixed In or Intended Fix Version fields to determine whether any versions have a planned or permanent fix.

The workaround is to import the attached sys_script_include_0170ba82dbd1c4503d1e623b4b96198c.xml . This script executes the same behavior as the mapping rules and should solve the problem for the customer. So you need to invoke this script include using the OOTB PostTransformHandler script. Perform the following actions:

Import the attached script include ( sys_script_include_0170ba82dbd1c4503d1e623b4b96198c.xml ) Go to script includes and look for EvtMgmtCustom_PostTransformHandler. It is an OOTB script include. Activate the script 'EvtMgmtCustom_PostTransformHandler' (using Active checkbox) On EvtMgmtCustom_PostTransformHandler script include, inside postTransformHandler function add the following:

(function postTransformHandler(event, origEventSysId){ gs.log('PostTransformHandler custom script is active'); try { var transformer = new TransformEventFieldMapping(); transformer.transform(event); } catch (error) { gs.error(error, ' failure with transform'); } return true; })(event, origEventSysId);

so basically, you should add only this part: try { var transformer = new TransformEventFieldMapping(); transformer.transform(event); } catch (error) { gs.error(error, ' failure with transform'); }
