Solution

all I found so far is this nifi issue here.

If you find a nice workaround or simple solution please let me know :)

Greetings Oliver

EDIT:

Just found this Issue. I applied the changes in my own start.sh and it worked.

if [ -n "${NIFI_SENSITIVE_PROPS_KEY}" ]; then
    prop_replace 'nifi.sensitive.props.key' "${NIFI_SENSITIVE_PROPS_KEY}"
