상세 보기 ERR_SOCKET_BAD_PORTAn invalid port number was specified for a network operation.
The port number is outside the valid range (0-65535), is NaN, or is not an integer. This happens when environment variables are not parsed correctly, or when configuration files contain invalid port values.
Ensure the port is an integer between 0 and 65535. Parse port values with parseInt(process.env.PORT, 10) and validate the result. Provide a default fallback: const port = parseInt(env.PORT) || 3000.
