Line 9 in 907f4d7

HEADLESS_CLIENTS_PROFILE="$profile-hc-$i" # valid placeholders: $profile, $i, $ii

HEADLESS_CLIENTS_PROFILE="headlessclient$ii"

now prints WARN[0000] The "ii" variable is not set. Defaulting to a blank string. in Docker Compose version v2.18.1 (possibly earlier).

Not sure how to best solve this yet.
