# An invalid command-line option was provided

You might provide a small number of arguments when running the `bin/start-server` command, but in most cases, none are required. If you provided one or more command-line arguments for the `bin/start-server` command, and any one of them is not recognized, then the server provides an error message indicating that an argument was not recognized and displays version information. In that case, correct or remove the invalid argument and try to start the server again.
