I am trying to set up locally Strapi v4 with PostgreSQL DB. PostgreSQL has been successfully connected, but unfortunately i can not configure APP_KEYS environment variable (.env).
I have downloaded this sample app from Render Cloud https://github.com/render-examples/strapi-postgres and that is the reason for the following bug.
I know that the format should be APP_KEYS=['key1','key2'], but i do not know what exact value and how that value should be specified?
Regards
