The Crashed Daemon

A critical web application has gone down. The Python HTTP server at /opt/webapp/ refuses to start because its configuration file is broken. Your job is to investigate the config, fix the issue, and get the server responding on port 8080. The server script is at /opt/webapp/server.py and reads its config from /opt/webapp/config.json. A wrapper script at /opt/webapp/run.sh starts the server. Hint: JSON is very strict about syntax. Even a single missing comma will break it.
