Currently n8n wants to start without setup. Here btw a temporary configuration is used to document my nodes automatically.
I use /workflows/demo which always changes to /setup automatically.
Hey @lublak,
Does setting N8N_PERSONALIZATION_ENABLED and N8N_USER_MANAGEMENT_DISABLED to false work?
N8N_PERSONALIZATION_ENABLED to false
and
N8N_USER_MANAGEMENT_DISABLED to true
works fine 
That is good to know, They are the only 2 settings that I though might be causing an issue
