Gateway script MessageHandlerException, project 'Project6', message handler 'threadHandler': com.inductiveautomation.ignition.common.script.message.MessageHandlerException: MessageHandlerManager is null in ScriptConfig!
This error occurs when a message is sent at the same that the project containing the destination message handler is saved. I assume because the save process is to recreate the message handler, AKA, delete and create. For message handlers that are processing many requests per second, this causes the problem that events are missed. Is there any way to queue these messages and send them once the message handler is successfully recreated?
