do you thing this bug could be rely to the script initialization race: > [@\[bug-3893\]Message Handler null in ScriptConfig during project save](https://forum.inductiveautomation.com/t/bug-3893-message-handler-null-in-scriptconfig-during-project-save/49995): > > 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 sec… I have it often with 8.1.48 and I search for a workaround... When it occur some script tag expression are broken until gateway restart.... --- _[View the full topic](https://forum.inductiveautomation.com/t/ign-6503-project-library-script-initialization-races/98636)._
