3682652 - On-prem extractor config.env file containing commented out lines makes on-prem package fail to work properly

On-prem logs contain exceptions like:
Factory method 'httpClient' threw exception with message: Invalid value for proxy port

and/or

Can't establish websocket connection to server (retries = n, next attempt in nnnn ms)
org.springframework.web.util.InvalidUrlException: Bad authority

Add commented out lines in the config.env

• Remove all unwanted lines from the config.env file. Commenting them out is not a solution - they need to be deleted completely.
• Check for linefeeds within the parameter values. For example, there should be no linefeeds splitting the EXTRACTOR_SECRET into multiple lines.
• The only allowed lines should start with:
  ########### PLEASE INCLUDE YOUR EXTRACTOR ON-PREM CONFIGURATION BELOW #####################
  EXTRACTOR_ID=
  EXTRACTOR_SECRET=
  WEBSOCKET_SERVER_ADDRESS=
  PROXY_HOST=
  PROXY_PORT=
  PROXY_USER=
  PROXY_PASSWORD=
