Information on your n8n setup
n8n version: 0.210.2
Running n8n via [Docker, npm, n8n.cloud, desktop app]: Docker
n8n is getting a message back from the container to say it doesn’t have permission to write to the folder, n8n itself doesn’t run as root which could be why you are seeing an issue, You could try changing the OS permissions on the /files folder but I think to start with it might be worth opening an interactive session with the container to make sure the /files folder has mounted and to see if you can do anything in it.
