Posting duplicati backup events to Slack channel

That would help me achieve what I want. However, the DUPLICATI__PARSED_RESULT is not shown to me, only these:

DUPLICATI__backup_name=nodered
DUPLICATI__block_hash_algorithm=SHA256
DUPLICATI__blocksize=102400b
DUPLICATI__compression_module=zip
DUPLICATI__dblock_size=50mb
DUPLICATI__dbpath=/config/ZSXXMASDPH.sqlite
DUPLICATI__disable_module=console-password-input
DUPLICATI__encryption_module=aes
DUPLICATI__EVENTNAME=AFTER
DUPLICATI__file_hash_algorithm=SHA256
DUPLICATI__keep_time=1M
DUPLICATI__LOCALPATH=/source/nodered/data/
DUPLICATI__main_action=Backup
DUPLICATI__OPERATIONNAME=Backup
DUPLICATI__passphrase=OBFUSCATED
DUPLICATI__REMOTEURL=googledrive://nodered?authid=OBFUSCATED
DUPLICATI__RESULTFILE=/tmp/dup-33ef979a-d629-4257-93a7-f7cb44cc2ef3
DUPLICATI__run_script_after=/config/slack_msg.sh
DUPLICATI__throttle_download=
DUPLICATI__throttle_upload=

Could this be a bug? I’m running duplicati version 2.0.2.1 from the docker container provided by linuxserver.io.

Update: just found out that this variable was added on September 1st. I’ll try to update my duplicati (read: build my own container).
