I have deployed N8N via docker on my local computer, but why is it that when I edit Workflow, if there is no operation for a few minutes, an error will be reported and the produced content cannot be saved?
All you need to do is log in to your account again.
I have seen this a few times. In some circumstances reloading the whole page cleared it up. In one case I had multiple browser tabs opened to the same n8n instance through different paths (one direct to the hostname and another to the fully qualified domain name through traefik). After I hunted down all the duplicates and closed all but one, the “logout” behavior stopped.
