unexpected argument '--ws-port' found

Question

I am preparing local relay chain from this tutorial. Configure polkadot and added raw-local-chainspec.json file but while running first validator, it gives this error.

ganesholi@Ganeshs-MacBook-Air polkadot % ./target/release/polkadot \
--alice \
--validator \
--base-path /tmp/relay/alice \
--chain /tmp/raw-local-chainspec.json \
--port 30333 \
--ws-port 9944
error: unexpected argument '--ws-port' found

  tip: a similar argument exists: '--workers-path'

Usage: polkadot --alice --validator --port <PORT> --workers-path <PATH> <--chain <CHAIN_SPEC>|--dev|--base-path <PATH>|--log <LOG_PATTERN>...|--detailed-log-output|--disable-log-color|--enable-log-reloading|--tracing-targets <TARGETS>|--tracing-receiver <RECEIVER>>

For more information, try '--help'.

This release removes the following CLI parameters:

--ws-port is replaced by --rpc-port. You can confirm this from here
