WARN[0000] The "ajk" variable is not set. Defaulting to a blank string

Hello,

using

sudo docker compose up -d

with the “Base version - apache” composer-file from docs/README.md at master · docker-library/docs · GitHub on a RaspberryPi, I get a warning 3 times:

WARN[0000] The “ajk” variable is not set. Defaulting to a blank string.
WARN[0000] The “ajk” variable is not set. Defaulting to a blank string.
WARN[0000] The “ajk” variable is not set. Defaulting to a blank string.

I couldn’t find any help what this might mean. Nextcloud seem to start and work correctly, but I guess the warning has a reason :wink: So any ideas what this could mean?

Found it: I used the string …$ajk… in the mysql-password, it seems that nextcloud is using that directly inside php without escaping.
