Answer №1

This indicates that the 127.0.0.1:8000 host has already been utilized by a different application. You will need to modify the host of your current application or terminate the mentioned one.

Answer №2

EADDRINUSE indicates that the port number being attempted to bind by the listen() function is currently occupied. Consider trying a different port number or terminating any other program utilizing that port.
