Business Rule not triggering subflow when “Assigned To” (reference field) changes — only works cmnt

[Satyam123]

Hi everyone 👋

I’m working on a Business Rule that triggers a subflow (global.update_jira_ticket) whenever either:

• Jira Communication (u_communication) changes, or

• Case Owner (assigned_to) changes.

The subflow should receive:

• input2 → Reference to sys_user (from assigned_to)

• input5 → String (u_jira_id)

• jira_communication → String (optional comment text)

  (function executeRule(current, previous /*null when async*/) {
  try {
  gs.addInfoMessage("From BR start");

  // Skip if Jira ID is empty
  if (!current.u_jira_id) {
  gs.info("BR: Skipping flow because Jira ID is empty");
  return;
  }

  var inputs = {};

  // Jira ID (string)
  inputs['input5'] = current.u_jira_id + '';

  // Case Owner (Assigned To) - Reference.User
  if (current.assigned_to.changes()) {
  inputs['input2'] = current.assigned_to; // passes sys_id reference
  gs.info("Assigned To changed: " + current.assigned_to.getDisplayValue());
  } else {
  inputs['input2'] = '';
  }

  // Jira Communication
  if (current.u_communication.changes()) {
  inputs['jira_communication'] = current.u_communication.getDisplayValue() || '';
  gs.info("Jira Communication changed: " + inputs['jira_communication']);
  } else {
  inputs['jira_communication'] = '';
  }

  gs.info("Inputs sent to flow: " + JSON.stringify({
  input2: '' + inputs['input2'],
  input5: inputs['input5'],
  jira_communication: inputs['jira_communication']
  }));

  // Trigger subflow asynchronously
  sn_fd.FlowAPI.getRunner()
  .subflow('global.update_jira_ticket')
  .inBackground()
  .withInputs(inputs)
  .run();

  gs.info("Subflow triggered successfully");

  } catch (ex) {
  gs.error("Error in BR: " + ex.message);
  }
  })(current, previous);

  🔍 What I’ve Tried

  • Passing current.assigned_to directly (sys_id)

  • Passing current.assigned_to.toString()

  • Verified input2 in subflow is Reference.User

  • Verified the BR “When to run” condition includes Case Owner changes

  • Tested with inForeground() instead of inBackground() — same result
