[Bug Fix] Handle "Mid-flight" Crashing due to node-fetch error in NodeJS Helper Library

[TanmoySG]

Describe the bug

• Mid-flight crashing
  • If the Monitor goes down, for any reason , the logging library also causes the app/program its logging for to go down, mid flight.
  • Caused due to FetchError in node-fetchwhen server is unreachable.
  • This should be worked on and rather than making the program stop it should handle it
  • May add a catch block to handle this

To Reproduce Steps to reproduce the behavior:

1. Run Monitor, in the main project directory - node .
2. In a separate terminal, Go to ./libraries/js/examples
3. Run the Example Server node . , should be running in localhost:8096
4. In another terminal , using cURL request to the example app endpoint and publish sample logs - curl localhost:8096/warn
5. Publishes sample logs
6. Now, in the terminal where monitor is running, stop the monitor using ctrl+c
7. Now try publishing the sample logs again curl localhost:8096/warn
8. This throws an error and stops the example app and it crashes.
9. The error:

Expected behavior Should be catching the FetchError and handle it, instead of causing the app to crash.
