Requirement to stop sending default abandoned chat messages in ServiceNowIssue Abandoned chat messages (e.g., 'It seems you have left the conversation') continue to appear in Microsoft Teams VA chats despite clearing system properties and deleting related sys_ui_message records. Facts By design, the platform does not treat a blank property value as a suppression signal of abandoned chat message and hence falls back to a hardcoded default, which is - 'It seems you have left the conversation' Release All Cause Root Cause on how it actually worked for the customer -The issue was caused by platform caching behavior. The temporary success occurred until a cache reset (e.g., due to an upgrade) caused the behavior to regress. Resolution Steps to Resolve1. Set the system property com.glide.cs.conversation_faulted_reason to a temporary non-blank value (e.g., 'time out') and save.2. Immediately clear the value to be blank and save again.3. Verify that the abandoned message no longer appears after the conversation is faulted by the timeout job.Note: This workaround may need to be reapplied after platform upgrades, patches, or node restarts due to caching behavior.
