Receiving error when trying to specify a port when running

[cvlehe]

What happened?

When running react-native rnx-start --port 62536 I receive the following error:

error options.port should be >= 0 and < 65536. Received type number (NaN).
RangeError [ERR_SOCKET_BAD_PORT]: options.port should be >= 0 and < 65536. Received type number (NaN).
