Is it possible to set environment variables in my self-hosted n8n workflow?
I am using a compose.yaml file to run my self-hosted n8n and I want to use the .env to store my sensitive information and use it in any workflow. I used the attribute env_file but it is still not working. When trying to create the env variable in the UI there is a warning message that says basically I have to pay to use this feature. How do you use you env variables in your workflows?
