Just followed the install instructions using helm chart.

i've configured a password for mysql connection and kubevious loads it properly

  envFrom:
     - configMapRef:
          name: {{ .Values.mysql.name }}-client

but this password is not configured into the mysql statefulset.

   env:
        - name: MYSQL_DATABASE
          value: kubevious
        - name: MYSQL_ALLOW_EMPTY_PASSWORD
          value: "1"

This cause an error on kubevious stating Error 500: Not Connected
