Bug Fixes

Release 321 contains multiple bug fixes:

Referenced Ticket Description
PLAT-44666 Fixed an issue where the MQTT broker would refuse a subscription, causing OPCH to retry a limited number of times and eventually trigger repetitive restarts. The system now handles subscription failures more gracefully to avoid unnecessary restarts.
PLAT-44858 Fixed an issue in how Connector Function outputs are handled for an optional list of empty child elements which was sometimes sent in a way that could cause issues.
PLAT-44745 Fixed an issue where the On-prem Connector Host used too much memory while being disconnected from the Tulip cloud.
PLAT-43477 Fixes a rare issue where apps where assigned to stations without an app id. This can cause apps to show up in the app dropdown without a name, which can cause confusion or inability to go to that app.
