Cannot start json-server with forever on ubuntu - json

Question

I am using below command to start json-server forever on my ubuntu:
forever start /usr/local/bin/json-server --watch db.json --port 3001
But as I list all processes using forever list, I see that the process is stopped. I have also tried to set --host flag by putting my private instance ip, but that is also not working. Can you help me to start the json-server correctly?
Below are the logs:
error: Script restart attempt #1

i can confirm that I am running the command in the same folder as that of db.json.
I also get below warning:

warn: --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms

I have some more logs:
Cannot bind to the port 3002. Please specify another port number either through --port argument or through the json-server.json configuration file

I have tried using other ports as well but that is also not working.
