No matter what it ends up with below error

python: init
Traceback (most recent call last):
File "/home/lenovo/Desktop/Digital-Beings/server/grpc/handler.py", line 45, in init
self.server = server('127.0.0.1', int(os.getenv('TCP_PORT')), self)
File "/home/lenovo/Desktop/Digital-Beings/server/grpc/tcpServer.py", line 10, in init
self._socket.bind((host, port))
OSError: [Errno 98] Address already in use

i am trying to run it with non docker method and when i do npm run start it ends up with above error. if someone could help me to run it that would be great!
