spodcast-spodcast-cron-1  | crond: USER root pid  34 cmd SPODCAST_ROOT="/data" SPODCAST_HTML="/data/html" SPODCAST_CONFIG_JSON="/data/spodcast.json" SPOTIFY_CREDS_JSON="/data/creds.json" SPOTIFY_RC_PATH="/data/spotify.rc" **SPOTIFY_PASSWORD="pnI7**

spodcast-spodcast-cron-1  | crond: USER root pid  35 cmd chown -R 101:101 /data/html
spodcast-spodcast-cron-1  | /bin/bash: -c: line 1: unexpected EOF while looking for matching `"'
spodcast-spodcast-cron-1  | /bin/bash: -c: line 2: syntax error: unexpected end of file
spodcast-spodcast-cron-1  | crond: wakeup dt=10

the next char in my password 'pnl7' is a symbol, #! to be precise. This caused issues when running with docker-compose.yml. Having changed my password to a more simple password, all is well using the provided compose.
